Should be pretty easy to provide ignoreincompat checks mods with just the mod.cfg overriding them.

Sadly, no, there isn't which is why I don't think it's a good first task. For the animations you can use this blend https://trac.wildfiregames.com/browser/art_source/trunk/art/meshes and animations/skeletal/biped_meshes_and_animations.zip

Preset hotkey profiles would be a genuine quality-of-life win, especially for players coming from other RTS games who already have years of muscle memory. Right now rebinding every key by hand is the tax you pay for switching, and most people just give up and play handicapped. Shipping two or three sensible presets — the current default, a grid-style layout, and maybe a classic StarCraft/AoE-flavored set — would lower the entry barrier without taking anything away from players who like the existing scheme. It also gives the tutorial something concrete to point at instead of a wall of unbound keys.

thank you for the info. I'll start from the top:  Renders to decorate for the campaign menus. Is there any requirements/suggestions/desire?:  Stylo AoE or older games (camera angle, painted style)? Objects? (book, sorrow, bowl,ancient bottles) / essential items? Quantity?  is there a guide line/story to follow?
