I made a select-to-copy app [https://pluks.app]. I recently realised copy paste is a 4 step process on mac (natively) - select copy (CMD+C) and then activating the window to be pasted in then CMD V, a simple select to copy and deep click paste will bring this action that we do maybe 100 times a day to 2 steps from 4. Solved it for my own use. Sharing here in case anybody else feels like trying this out.
