I'd suggest using the search feature to see if ideas that you have, have already been brought up before. For example, the editor/tool kit has already been brought up like 3 or 4 times, maybe more, in multiple forums.

Larian does read these forums, or at least I would assume so (since they post here and stuff like that ;)) since they advertise on their kickstarter campaign that you can show your ideas and stuff about the game on this forum.

You can also still post your ideas on here:
http://larian.uservoice.com/forums/314766-divinity-original-sin-2-game-ideas

and vote on ones that you want to see in the game too (I'd also suggest using the search feature there too).

I'm not sure what you mean by 'Respawning' though, could you elaborate on what you want to have implemented? From my understanding 'Respawning' would make the game easier, for example if you died, you could just go back to the area you were just at and try again.
