I was wondering if there was a fast way to clear a layer/canvas? Autodesk has a corner double-tap and medibang has a single button on the tool bar. I like to sketch fast and go through a lot of preliminary ones I just discard and move on to the next. The only way Ive found so far is to navigete to layer panel and clear it manually from the drop down menu or to make a new canvas. Its not exactly the best for keeping up a flow, though. I'm using the most updates version for Android on a galaxy tab a 10.1.
