Just a feature suggestion, Scroll capture would be really nice.

If scroll capturing is possible to implement this app would be really great. Another thing that would be nice is being able to change the size of the drawing pen and having a custom color picking thing.

The issue names no files, tests, or entry points. Start by inspecting the Android screenshot-capture and drawing flows to determine whether scroll capture, pen sizing, and custom color selection are separate deliverables. Done would require an agreed scope and acceptance criteria for each requested feature.
