This looks pretty nicely done, and that it could be a nice note app. Tagging + version history are pretty nice features to have in a Note app, and I like that this is a lot lighter weight than Evernote or OneNote. I use OneNote for everything for work, and some things for home/personal projects, but I'd rather just have another, dedicated, lighter-weight solution for home/personal stuff (and I don't love Evernote), so I'm excited about this.

I just bought the iOS & OS X versions to play around with, and I have three suggestions, if I may be so bold:

- When quitting & reopening Note, I'd love to see my last few notes automatically reopened (whatever notes I had open before I closed the app) and positioned where they were. Kind of like Stickies.

- Make the screenshots of the apps more prominent in some way on your landing page, and make the feature descriptions (e.g., under "Editing History, Multiple Tags, iCloud sync" more readable).

- Ditch the black "LKMAKE" splash screen on the iOS version; it's jarring to go from a full black screen to a full white screen when an app starts up.

And a bug report :)

- I don't see notes from OS X syncing over to iOS, or vice versa. iCloud is enabled for Note on both iOS and OS X, so something doesn't seem to be working right here.

And finally, a crazy idea that I would totally pay extra for:

- Ability to add notes to Note from the command line. Seriously. I would love to be able to do this from my terminal:

note "Buy bread" -tags home, groceries

I know you can't integrate with iCloud outside of iOS/OS X App Store apps, but I think you could build this pretty easily by having some backend web service that notes get sent to, and when your iOS/OS X app starts up, it just downloads new notes and adds them into the app, so it appears like a normal sync. Hell, I'd be willing to build the backend for you.

Nice job and good luck!
