  I'm in principle quite OK with this minus that other patch I need to be written first to move DragHelper out into the lib (see other comment). Pitch: If you do that, it'll make it much easier to make the other menus (and other things) act similarly later, with smaller patches there.
  
  However we need a collective decision that this way to handle tap-and-hold is the one we want to go forward with - this patch basically makes a call to resolve T10783 <https://phabricator.kde.org/T10783> in a particular way - and needs some more buy-in e.g. from @mart for that reason.

I'm not happy with hardcoding these values. If we decide to do touch drag this way, we're going to see this being duplicated all around the codebase - with subtly different values, etc. If we want it that way we should centralize it somewhere.

We probably need to put DragHelper to plasma-framework - there's similar classes in FV and TM too we can consolidate. This isn't that much work and I'll gladly help mentoring the patch.
