ZDoom

I agree, it would be useful too.

The feature is already planned for a future version of EDGE (through the HUD.DDF file). So why not add it here? A HUDINFO lump would be cool.

I approve to this suggestion, it is a great idea, eg So you can put the Inventory bar somewhere else.

I don't expect this to be implemented any time soon, be it in the official or unofficial builds, but I think this is something that ZDoom can really benefit from in the long run, for future mods.

A text lump or scripting language of sorts that lets you customize the HUD and the game menus (when you press Esc) completely. Doom 3 has it, I think the Eternity engine source port has it too, having it in ZDoom will only make things better.

Just a suggestion.
