See the attached patch for ExoIconView, that should do the trick for the
icon view. For the details view, GtkTreeView offers a hover-selection
setting, but that doesn't work for multi-selection mode and it'll also
select the row right away without any timeout. I could add an
ExoTreeView class, which extends GtkTreeView with the required single
click features.

Well, it depends on the complexity of the bug. The icon view selection
bug was really trivial, I just forgot to check for Control/Shift.
