EDIT: I REEEALY love this app a whole ton just from using it for a few minutes, despite a few hick-ups. That said, I want to apologize because my first reaction was to offer advice on how this could be improved to make it even better. I AM NOT COMPLAINING ABOUT IT! I think it's super awesome! And of course I didn't pay for it so I wouldn't have any right to complain even if I didn't like it. This app is very exciting and I'm sorry the first thing I let out of my mouth was a critique. Thank you so much, magicriggs!
I'm not a programmer, but from what I can tell the app works like this (when set for double click home button).
Home button pressed ---> Take screenshot. Wait for second press, after X amount of time, launches launcher set from within application.
In the HQ/rooted version, it takes a real screenshot. In the LQ version, it takes a shot of the app (The same thing Visual Task Switcher does). The second way of doing it can be easily differentiated from the other by whether you can see the notification panel in the top of the screenshot.
1) If Itching Thumb is bound to longpress home, and the launcher is set to single press, only LQ shots are taken. SOLUTION- set Itching Thumb as default launcher, leave longpress binding. HQ shots can now be taken (assuming root and permission granted).
2) If above solution is applied, pressing the home button while on the home screen causes X amount of time pause, then relaunches launcher. SOLUTION- DEV!- provide user-configurable double press home times. Setting it to 1ms would allow users to have longpress home key binding without the app having to be significantly rewritten to avoid this glitch. This will mask the issue, but ultimately it's still there. If there's any way the app could check to see if the launcher is already in the foreground, and defer the launchers preferred home key binding, that would be best.
3) Setting the default launcher from within the app is not under preferences. It's under "Help" and you need to click a link. This should be in preferences like Visual Task Switcher or QuickDesk.
4) (Personal Pref) I don't like the bottom bar with room for apps. It would be nice if this could be eliminated as either an option in the app or a ONLY_CARDS.apk I would be less resistant to it if there were a way to add access the app drawer straight from there.
