This app has some great tools and features but from an advanced user perspective, you do come across some workflow limitations because of the touch-only interface navigation. Enabling the use of any external bluetooth keyboard can alleviate these issues by using keyboard shortcuts to go back and forth between brushes and tools much more efficiently. Also key remapping could be useful in this case but just the addition of bluetooth keyboards in the style of the desktop Sketchbook app is enough to make this app more productive for advanced users.
