So the 10.5 slip isn't really that big of a deal I guess.
Here's my new plan, if you're interested. For the past 5ish months I've been working full time of FlySketch 2. With the news of the slippage, I'm going to start working on a VoodooPad 3.x (which will work fine on 10.4) since such an update is way overdue. After that, focus returns to FlySketch 2 which will still be 10.5 only.
I'm also considering renaming FlySketch 2, since it's such a big change from version 1. From my point of view, it really is a new app. If you've used both FS1 and FS2 and you've got an opinion on that- let me know. Is it a different app?
