AHKNIGHT  Notae runs slow because of a bug in Leopard's Spotlight service, unfortunately. I have located the cause and filed a bug with Apple.

What happens is that every time you change a note, Notae loads some data from disk (the NIB for the new note type). When that happens, Spotlight hits the disk hard for a little while and then comes back. So, unfortunately, it's nothing I can really control on my end.

It's bugging me too, surely. And for some people 10.5.1 helped a little, so be sure to update to that.  
(Version 2.2.1)

AHKNIGHT  Version 2.4.6.1 works on Leopard.  
(Version 2.4.6.1)

AHKNIGHT  It does not use or save any energy on any display type. The CRT still has to charge the screen to show black and any given LCD's primary energy suck is the backlight, which colors do not change, but brightness does.  
(Version 1.0.3)

AHKNIGHT  This thing is just molasses after about 5K transactions...  
(Version 2.1.6.3)

AHKNIGHT  Author: As with any new service in Mac OS X, one must logout and log back in for it to show up.  
(Version 1.2.2)

AHKNIGHT  The column width issue was resolved in 1.2.

AHKNIGHT  I've taken note of these things, but please use the suport forums on codepoetry.net rather than posting issues here. I don't look for bugs on third-party sites.  
(Version 1.1.1)

AHKNIGHT  Column widths will be added soon, yes.

The tags showing oddly is something Apple did. I'm looking into a solution for that.  
(Version 1.1.1)

AHKNIGHT  I opened the app and it threw up two modal dialogs and hung, solid, when I started to answer a question.

It's so bad you can't even use it.  I'm glad it has a demo period..  
(Version 2.9)

AHKNIGHT  Small window that hides in the corner of the screen, remote AppleEvents to the other machine running iTunes, and nothing to install on the "server." Slick and simple, I love it.

It loads your playlists and lets you pick the tracks if you desire. Volume slider and all.

Just remember to turn on remote apple events on the other computer for this to work.

I was going to write something like this and, lo, there it is. Good job, dev. :)
