HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

For a long time, I've been suffering from the random repositioning of hero icons in the corresponding menu (to the left of the castles). The main hero might be at the top, you take your turn, and he's at the very bottom. I know about the Alt key shortcut, which allows you to move the hero back to the top, but he can still slide down again. I played for a long time at 800x600, and I thought it was a problem with the old interface. I switched to 830x664, and it's the same. It seems like a small thing, but it's incredibly annoying. Also, when playing at 830x664 or higher (apparently), after upgrading Archers/Mages with Jellu or a Dragon, the resource menu doesn't update (gold doesn't decrease). You need to perform some action with the mouse to display the actual gold value. Apparently, since these heroes aren't used in Multiplayer, no one is fixing it. #Campaignheroeslivesmatter.

I came across an interesting picture on VK. In essence, there's nothing particularly interesting there, except for the ability to assign spells to hotkeys. It would be very convenient to use spells like Dimension Door, Teleport, or Oil of Speed, Resurrection in battle, without wasting time looking and flipping through the spellbook. Is it possible to implement something like this? Currently, the numbers 1-9 seem to be free. It would be great, I think.

In the unofficial patch-plugin for the HD mod by RoseCavalier:

there is such a function. In general, there are many interesting ideas there, but there are so many of them that it affects the stability of the game. Hotkeys aren't that convenient in practice; what is really needed is a turn sequence feature.
