Okay, so my two cents here.
First for the ones who don't know, I'm using RPG Maker since 2004, wrote a lot of stuff for VX, some for Ace, and right now I'm using MV a LOT lately. Soon you guys might see a game I'm programming with a partner. It's a wonderful piece of software, kudos for all the team behind. I already helped in the Portuguese translation several times (it started unofficially several years ago) and did some very extensive review for Ace and MV at the time of each launch (here for MV:

I see a lot of people being delusional with some requests here (please don't take it personally, I would also LOVE to have lots of these), but we know that, mostly, RPG Maker is a very conservative software and that's exactly the reason I love it, it's predictable and don't try to reinvent the wheel with The Next New Shiny Thing(tm) that eventually is left behind in a newer version.
Probably the feature set was set in stone already and now we would only receive small updates. Well, very well...
That being said, I think it's useless to ask things regarding resources/RTP or game engine ones. Mostly of the won't be used for a "serious developer" anyway, because they will want to focus on something original.
My stance is also a bit against "generators" because they, okay, give some freedom in making stuff that isn't included in default RTP/resources, but they also are a huge hit in creativity, because it locks us in a given style.
So, I would like to see focus in making the editor better, that should suffice.
No more arbitrary limitations, and it should be more flexible. Every time I want to use a resource different from specifications (e.g.: a face) the editor just breaks and that *fill with that word here*. If possible, some options like those, to change the defaults, would be more than welcome.
So, you decide the size, the amount of frames each thing has,
et al.
And obviously, make more options apparent and easily customizable, I don't want to search in a obscure part of the code something that should be changeable straight away, like screen resolution. And I say that being a coder. A safe bet also should be
different templates for creating a new project, I'm absolutely sick of creating new projects with no customizations and more of 400MB of resources that I won't use. If it's to wish too much,
create plugins that can customize the editor itself, instead of only pieces of code for in-game engine. But I know, that's a stretch.
On the suggestions the guys here gave, a better fit should be a
Trait-like condition page for events,
notes fields (for notetags) for the rest of the things that still don't have it for some reason, and I would call it a day. RPG Maker doesn't need a revolution, it would be an entirely different software. So, if it's still Javascript, thank God.
For the guys who are responsible, like
@Touchfuzzy, I'm in a big hope to work in the translation of the project (other guys like Raizen might also be interested). You guys did a wonderful job in MV and I don't expect less than from you guys!
