Also add Mel (from PS:M, with permission) and Mel (from the beta, would need custom animations since the original versions were removed).

We can't add Mel from Portal Stories, they've said they don't want people using that model. Beta Mel is just a reskin of P1 Chell, so they could be added...

Relates to #1679

This would be an interesting idea. It'd need new UIs in the app among other things, so this would be more of an app issue.

Why are you using BEE2 with TWTM anyway? You won't be able to use the time machine.

That happens because TWTM replaces the vanilla doors and cubes with it's versions. There aren't leaks in the doors - TWTM's doors are transparent. Because the doors aren't normally transparent,...

How about adding Co-op support? So you can have 2 actual players, and then 2 clones re-creating those players' actions!

Oh yeah, right. If TWTM co-op were added you wouldn't be able to shoot portals while replaying the recording.

Make sure to add the "future you" sign in TWTM Old Aperture maps.

No it's not. BEE1 doesn't have styles, or lots of items.
