Hi Chris,

for custom projects such as Maui, you should change the world's drop handler to fit your needs. It is very easy and avoids any conflict. Of course you can replicate some of the standard features if you want. For example, I did this for Vivide to open custom tools.

See PasteUpMorph >> #transferMorphConverter:

Just call it with a selector when Maui starts.

Best,
Marcel

If I understand this correctly, it'll probably conflict with Maui's
equivalent gesture, and only for the equivalent of dragging a splitter
bar all the way up to the top..?  (really, is it just substituting
that one DnD operation for another?)  Except it opens a new window,
too (which I'll have to later close?).  Maybe I'm missing something,
but it seems heavy and laborious for only what it does.  Hopefully the
hook can be customized..
