This is becoming a huge problem for the future. The issue is that just saying "we need touch gestures" is meaningless unless we know WHY Plasma needs touch gestures. Not as in "everyone else has it" but rather looking closer at what kind of experience we are trying to provide for touch users? Are we intending for it to be something someone sets up? Like a fake touch experience by editing widgets and extensions to make it mimic a touch experience or is this something we need to create?

IF it is something that we expect users to play around with and create themselves then just adding a wealth of touch gestures and leave what they do up to the user is the best call. IF on the other hand it is a larger experience then we need to accept that this has to be created first
