Thank you Sir Albe!
I always assumed that the Recruit All button and all other fancy stuff is H3SW, and that HDmod only allows the resolution change and doesn't bring any features, thus I would rather say it's from H3sW - but you are probably more knowledgeable about these topics and little differences.
When you build a Green Tower and clcik on the Green Tower itself it works properly, but if you click on the left bottom side on that recruit all button (that is great by the way) it is too tempting to not recruit Red Dragons from there
I hope I'll find more bugs and updates.
Another feature / gameplay upgrade you should do:There is one BIG BIG BIG hurdle that makes the game a little less fun to play, and I don't know why you guys didn't see it in the first place too.
When you are in battle, you very often need to quickly right click the enemy unit to see how much HP it has left, or just to check its stats. Sadly, when right clicking the box instead of just appearing for the duration of the click when you hold it, appears completely and you need to manually press "Okay" each time to exit this window.
It would be far better to make it like in all original heroes where if you right click you need to hold your mouse click and for that period of time all the stats and hp left is displayed.
Please do consider that for 0.82
