Is AoE2 DE's scenario editor not yet really up to snuff?

I recently decided to play around a bit with the editor, and I stumbled over a couple of things that seem to make it clear, that it was certainly not the focus of DE's QA team.

-Apparently the Cinematics tab is completely useless, as it is currently not possible to play any cinematics before or after a scenario. The selections you make here are simply ignored by the game. If you're making a custom campaign it is also not possible to display the scenario instructions on a so called 'card' beforehand like in the actual campaigns. The corresponding dropdown menu is completely empty! And I know for a fact you could easily choose any existing campaign backdrops for your own campaign scenario in the original game.

-Slightly related to that: the "map" for custom campaigns where you select your scenarios is completely white and empty. It seems like both this, and the flags representing the individual scenarios were at some point supposed to be customizable as well, but apparently that's not the case yet.

-Another thing that jumped out to me is how stupidly complicated it is to paly a sound. There is no dropdown menu, or any other kind of UI solution to pick out the sound you want. You have to manually type the sound event's name into the box. I don't know how one is supposed to figure out these names. Right now the only option seems to be a google spreadsheet that some kind soul provides in this Steam guide for the editor. I know it was probably like this in the originnal game as well, but there you could simply use the name of the individual sound file in the game forders. This is not possible now in DE, because the sound is stored differently. This just seems like a huge oversight, to not simplify the sound selection process.

-The third and final eyebrow raiser for me personally was the horrible german translation of the editor's interface, to the point where I had to google some options to figure out what they mean. I won't bore you with specific examples but it's the typical, technically correct 1:1 translation that makes absolutely no sense in the context. Reeks of Google translate, which is weird, because I haven't encountered such blunders in the rest of the game. I wouldn't be surprised, if other languages are facing the same problem in the editor. But even knowing the original english wording doesn't really help sometimes, so it's up to trial and error, to figure out what does what. Tooltips would help a lot here.

Right now it seems to me like the Editor in AoE2 DE was pretty much an afterthought. I don't really know how much they expanded its features compared to HD or even the original game, but there seems to be so much quality of life potential for DE that was just ignored and seems to be still missing today. The most recent list of bugs and other problems I could find was this post on AoK Heaven from december 2020.

Since I could barely find any information about this topic I wanted to ask you guys: Did you have similar expierences with the editor? Is the lackluster state of the editor generally known? Does anyone know if there are still improvements to be expected?
