Modding feedback wanted

[sube]

Don't know if it has already been mentioned, but I would like the possibility to mod populations.
Let's say that for instance I'd like to make a map or scenario where in province XXX it's possible to recruit units that I invented, orcs or elves or whatever. I think with 2.11 I could do it if I create these units by modding existing units, for instance replacing jade amazons with orcs. But I would like to add my units as populations without losing existing ones.

Another thing that I would like to have is an additional "send", we already have "send gems", "send money" etc., what I would like is also a "send units". After all, if my ally is in trouble, the best way to help him would be sending him directly units. Where these units will appear once sent (his capital? a neighbouring province?), that remains to be seen...

And... maybe a command to change cost of temples/labs?

Aaaand... the possibility to include special prophet tga sprites (as in the case of a demonbred, who changes sprite when becoming prophet)

And I'm sure I had more... However, sorry if these points have already been discussed, I've really no time to read every post
