actually, I've come up with some useful functionality for the general transfer buttons:
select a stack with a click, click the button - one unit remains in the selected stack, and the rest of the army is transferred.
this is a keyboard-free method of transferring while choosing to leave one unit.
as a non-competitive player, I like it this way.
And then I'll definitely remove the "intelligent" leaving of one unit - I'll make it so the weakest remains without needing selection.
Well, it seems this is indeed the optimal option.
A question has arisen.
Is it possible to convert one-way teleports into two-way ones after map generation?
If yes, I would really like that—optionally, of course, otherwise the original gameplay adepts will swarm in :) Right now I sometimes play WT not because I dislike SoD, but because of the one-ways; they often result in unplayable generations in SoD.
