I don't know how realistic of a request this is, but adding the ability to frame capture would be great. Example
And an even more unlikely request: GIF creation, from video and stills. Example
There are not many decent options for these two things on the Play Store.
When I need more accuracy than Timbre's touch controls provide, I use the uglier Frame Capture.
