Pretty sure that only moves the sprite, not the point of origin..?

Going to close this thread, because I don't think this goes anywhere nice nor productive anymore. Strictly speaking, having multiple accounts here is not allowed. Especially when caught trying to sockpuppet or attempting to evade (temp) bans. Otherwise I don't really care if someone wants to make a fresh start here for whatever reason. Unless I start to get more and more reports commenting on the same'ish behaviour that promped making a new account and my patience finally wears out.

Going a bit offtopic, but: I used to have a short invisible object in the wall on a (hidden) conveyor, that was prevented by travelling by being stuck on a in-world barrel. Destroying the barrel would release this object to travel over the conveyor and trigger actions (such as moving floors/ceilings) etc. It does require sacrificing a thingtype when aiming for ports with only dehacked support. And for best result the barrel ought to spawn a seperate explosion thing in order to make it look good (because the object becomes unstuck only at the last frame of the barrel's death sequence). And that makes it quite expensive in thingtype real estate.

Open UDB. File > Open Map. Browse to your Doom folder and select doom.wad. You'll then be presented with a popup window asking you to pick a map and game configuration. Pick your desired configuration (eg 'Doom: doom (doom format)') and click your map (in your case E1M2). And voila, you can edit that map. If you want a configuration other than 'doom format', you need to open the map in doom format first and convert it later to your desired format. This doesn't always go fully automatic, especially to UDMF format.

I'm running Dosbox regulary for ancient (doom) tools I'm still using.

To learn this kind of basic stuff, you open a regular vanilla level in UDB and see how it's done. There's also thirty years worth of tutorials available online, easily found with a simple Google search. So what exactly has you stumped here?

Wall textures used as flats in EE still need to have appropriate dimensions. Using a 16x128 wall texture as floor works; a 128x16 one does not. Yes, that kinda sucks.

Sure, there's the ACS function Teleport_NewMap.

No, you just did that.

The Door Problem

We do know. And if this was easy to fix, it would have been. There is some activity on this front but best not to divulge at this point.

If you don't get the verification email you should contact me.

This is me, every year :)
