DRDUL  I have been looking for a simple to do list app for a long time. Up 'til now I've been using Check Off, but the two problems I had with that app are that it's tied to the menubar (getting in the way of other apps), and there's no easy way to sync the data between my Macs.

I finally stumbled across TaskPaper, and I love it! It floats in its own window, so I can position my to do list anywhere on my screen. I'm a Dropbox user, so syncing is as easy as saving the to do list to my Dropbox. Most of all, though, I love the clean interface and simplicity of use. The screencast on the developer's website is a great intro to TaskPaper. One extremely useful thing the dev doesn't mention in the screencast, but which I found in the (very good) user's guide is that you can use the Tab key to indent tasks and notes, which will then be attached to the parent task (and move with it).

I also like that the appearance can be easily customized. The only tweaking I had to do to the "Standard" template was to bump up the base font a bit, and change the colour in which tags are displayed. One minor complaint is that although I used the preferences pane to tweak the font sizes and colours, I would have preferred to edit the template file directly, but could not find any documentation on the codes used in the file.

All in all, a fantastic app which has made it much easier for me to organize tasks.  
(Version 2.1)

RANDOMMAC  Simple, speedy and flexible.

The TaskPaper upgrade to 2.0 makes the difference between night and day for me. What was just an intriguing concept — a simple paper-look to do manager — is now my default note taking and to do manager.

I started out with iGTD, but got overwhelmed by the endless forms to fill. I like "Things", but never quite got comfortable with it. I tried OmniFocus, but Things and OF became ends in themselves, constant temptation to overfocus on the process and not on results.

I love TP2's speed and flexibility. It doesn't tax my aging PowerBook, it gives me very little to distract me, yet makes it easy to customize tags on the fly. The ability to narrow my focus is essential, and TP makes that easy. Jumping back and forth between individual projects or contexts and the project list is smooth and fast.

Thanks, Hog Bay, for making the upgrade from 1.0 to 2.0 free. I wasn't even going to try it out, but the online tutorial sold me. If you haven't watched it, do so now! Then download the demo and try it yourself.

MAC ATTACKS  Sometimes technology can be a hindrance to progress. Why wrestle with a sophisticated GTD system to keep track of your own simple day-to-day tasks when Task Paper can do everything you need so simply and quickly?

I always used to maintain simple text files for my to-do lists so Task Paper was a very easy and natural progression for me. Yes, it's not got a lot of whistles and bells but it really doesn't need them. In a way, its sheer simplicity is what makes it so useful.

What makes it even better is that there also exists a Windows sister application (called To Do Paper) which uses exactly the same underlying text format so I can seamlessly access my task lists from both work and home. All I need now is an iTouch version and my life will be complete.

HOWEVER...it's a shame that I have to shell out $29.99 twice for the same product on two different formats - why can't there be a second purchase discount arrangement between the authors of the Mac and Windows versions?

ELIOTWHITE  Is there an upgrade option for moving from 1.x to 2.0? I couldn't find any relevant information on Hog Bay Software's site.

GLOBETROTTERDK  I would really like to see a TaskPaper iPhone app.  
(Version 1.0.3)

TEKL  It would be nice to have a global hotkey to toggle visibility of TaskPaper. I would like to use F16 for that.  
(Version 1.0.3)

AETNARIA  Any chance that an 'Archive Done Projects' feature will be added before the 2.0 update? I have a bunch of empty projects I have to scroll through to reach others now, since all their tasks have been marked done and moved to the Archive.

The only clean-up option I can find is to drag the cursor over the project's name (since a double-click triggers the single-click phenomenon) and hit delete to remove them entirely. Given that tasks can be archived, is there no better way?

VERYVITO  TaskPaper is the ToDo list I've been looking for: It actually replaces the pocket-sized notebook I've kept on my desk for years -- and is just as simple to use.

It doesn't do a whole lot (thankfully!), but what it does do, it does great.

IGAUCHO  TaskPaper is an excellent alternative to the new swarm of GTD apps hitting the Mac market. There are some great choices out there. Personally I have been an iGTD user since the start, but this one really is simple and allows you to organize your tasks quickly and get started on them. It helps to avoid the hassle of over-organizing things. TaskPaper is really in its infancy still but it is backed by a very responsive developer who is burning the midnight oil to make it better constantly. Version 1.1 is supposed to bring some huge improvements and new features. Can't wait!

There are a couple features that it is missing that would make it an absolute top contender (most are echoed on the Hog Bay forums). It really needs sub-tasks, drag and drop reordering of tasks and projects, iCal syncing, and .Mac support. Aside from those few shortcomings, I enjoy using it.

GLOBETROTTERDK  I just purchased TaskPaper as a MacUpdate Promo. I went into the Hog Bay software forum to find an answer to a question I had and found the following comment from Jesse:

"I'm very likely to move new development ie version 1.1 to Leopard only..."

Maybe this should have been mentioned in connection with the MacUpdate Promo? Quite an important piece of info for anyone not planning to upgrade to Leopard right away! As far as I know, this is the only app that is planning to go "Leopard only" at this stage.
