It's an idea to post that in the "About" section of the Workshop area?

This is pretty lame, I can't use blender, it's a giant head F**K for someone like me, I am too old to memorise a language worth of nonsensical terminology, and when I was young I wasn't great at figuring out what the stupid terms meant in software ether but I still managed to make some great maps with Duke Nukem and later Quakes build engine, it was all set up for me, I wasn't told "hey go and give making a map with 6 different programs that all have bits and peaces of it you will need to make a map, then you just need to go online and look for textures and tools for filters and ad on's, WTF WHY?
The sort of people that are good at figuring out how to make maps have usually got ♥♥♥♥ for brains, they like making mods for games, but they don't actually play the game, this is what I've found from a game called Besiege, the mods are so badly thought out, or maybe these mod makers are dealing with something that is over the top, complex for no reason, like the building thing that comes with the game Teardown, it's got a confusing building system. I shouldn't be ♥♥♥♥♥♥♥♥ to you about this LOL sorry.

I don't see much chance to have an integrated level editor, that's a very hard to do from a dev perspective. Doom, Heretic, Duke Nukem and build engine games, Quake etc. they had a ♥♥♥♥ ton of editors, Blender is... a whole different level. I hope someone will post some basic level editor tutorials on youtube sooner or later.

even if they did it, it would still be too much for me to understand, I've tried to make short animations in adobe photoshit and I could once make gif files easy enough, now It's full of screwed terminology and the default setup is just retarded, seems to me all software has turned into ♥♥♥♥,my phone I hate,wish I could go back to the first I phone, now it's (rotting) Apple updates that kill your phone, windows 11 is probably the worst it's been, it blue screened me today and it has auto updates that are really just for mining meta data, it is a window without windows it's now a cloudy day at Microsoftcocks, god I hate this world. Oh well, I don't complain about it LOL

Jesus I'm lost, I can't understand why everything needs to be such a ball breaker

I give up
