ROBOTANK  From the developer's site: "sidenote is no longer supported until the end of my PhD Thesis in January 2010, that is eating up all my free time. Updates are planned, thanks for your understanding and support !"

If anyone was wondering, as I was, whether sidenote is dead, here's our answer! I'm not sure how the current version works on Snow Leopard, but I guess I'll give it a try.  
(Version 1.7.3)

AARGL  I'm on 10.4.11 and I must say that Sidenote doesn't always appear when I move to the edge of the screen (maybe some conflict with other apps... ???), but with the shortcut it's ok.

My main goal was to find a drawer staying invisible to store in it SMILEYS to integrate in my mails, and it does the job perfectly, so, even if it wasn't intended as its main purpose it's perfect for me!  
(Version 1.7.3)

WHITEMERE  Absolutely great app - used it for a few years now and is so simple and efficient you forget it's not just part of the OS.

For those having trouble using it with Leopard straycat posted a fix on the developer's homepage: http://stashbox.org/217632/sidenote.app.zip

I find that version works absolutely fine for me now as of 10.5.6 (i.e. no strange blue arrows in expose, sidenote slips in and out just by mousing over the screen edge again instead of having to 'select' it from expose etc.)

Still not so good with spaces apparently but as I don't use spaces I don't find that a problem.

BOBBYKNOX  Very useful to quickly jot down ideas and TODOs.

SUPERC  I LOVE Sidenote, however since my update to leopard, it seems a little buggy. I have spaces turned OFF and I still have to "choose" the application in expose in order to gain access to the drawer. I hope that these issues will be addressed in future updates!

Thanks again for a great, useful, program.

DNEM41  i just want to start out by pointing out that this is a 5 out of 5 overall, and that i gave EOU and features rating a 4 and a 2 respectively. thats because im hoping the people who made this will pay attention to these because this app is so close to being the perfect note-taker:

- i would like the ability to copy and paste screenshots into and out of the note when it pops up. sometimes i just need to hold a screenshot where i can see it until i decide where i want to use it for good. in essence the note-taker would act as a visual clipboard.

- i wish i could adjust the timing of the open and close separately. it gives me the option to choose whether i want to open with hotkeys only or close with hotkeys only, but it groups the popup/close delay as one setting. sometimes i would like it to open faster and close slower using my mouse. that way i can use my mouse to bring it up immediately and go and grab what i want to paste it into the note w/out it closing on me real fast.

- yes i would like the option not to have/adjust the auto-save option. i usually end up saving it manually if i think its that important anyway.

-overall, using the drag menu to navigate between notes when the note is open is pretty easy.

- i do wish that right underneath the drag menu, the icons were on the bottom instead. if this would get rid of the drag pad that is already at the bottom, then this would be a problem (since i like to sometimes move it up and down the side), but maybe the drag space can be put somewhere else (or hopefully it wouldnt interfere with it).

- yes, the expose thing is annoying but i can deal w/ it in the shortrun

this is like the only 6 things out of the maybe 8 that are stopping this from being the most functional/useful note-taking app out there. its already the best, in my opinion, but that doesnt mean it cant still be made better.  
(Version 1.7.3)

FAYYAZB  I used to love it till I upgraded to Leopard and all my default note NOTES have suddenly cleared out. I had a backup but today again all my notes are my empty. I think I have to look for a good alternative till Sidenote is upgraded.  
(Version 1.7.3)

N0ISE  this prog ROCKS!!im becoming addicted to it..never miss a note! A++++++++++++++++++++++++  
(Version 1.7.3)

CLEVERSIMON  Seeing some strange Exposé behaviour with sidenote 1.7.3 and Leopard: the white rectangle w/ blue arrows the appears when you animate a screen-edge change pops in when I try to show all windows. Not a deal-breaker by any means, but kind of annoying.  
(Version 1.7.3)

ONLOOKER  This is a fabulous program. First, it seems utterly reliable. In two years of use it's never lost any data. It autosaves, but you can force a save if you want. Second, it's always just there, at the edge of the screen. That means no switching, moving windows, whatever. It really does seem to be the fastest way to store and retrieve information I've found. Just one simple move of the mouse and the drawer slides smoothly out. And that smoothness seems to characterize sidєɳotє.
