Thanks for bringing this up!
I think the most user-friendly way would be to add a preferences
option regarding this, e.g. a checkbox labelled "Mouse Button 2
(middle button) Pastes Current Text". However, cluttering up the
config dialog is also something to be avoided, and now that I think of
it, most users will probably not understand what that's for anyways.
We could just add this as a config option which can be manually
changed in the config files, without a way to change it in the config
dialogs. This way power users who want to change the behavior have a
relatively easy way, but others are not bothered with this option.
It seems to me that scrolling with Mouse Button 2 would be the
expected behavior for most users these days. Maybe this should be the
default? (If we do this, we could still consider making the 'paste'
functionality available via a config option.)
