Well, if the next RPG Maker installment could have more than a Windows version, it would be cool. Some other parts of the basic engine need to be redesigned too. The options dialog is terrible and too restrictive, for example.
I don't know why this dialog has been there all this time. Just changing 1/2 useless options at the main tab. I've made a mockup. You know, having ideas for anything is free!
Also getting rid of Ruby. It's terrible. Or maybe using a better implementation (if there's any, I'm sorry, IDK). I've heard that mruby is faster than Ruby on Rails. But I know nothing. Outside of RPG Maker I don't care about Ruby.
EDIT:
There needs to be a more convenient way to put scripts into a project. It literally takes about 30 min to an hour to load in all the scripts I need, because of the tiring manual method of script adding currently available in Ace. It's not difficult, but it's time-consuming. Some sort of batch-style adding would be splendid.
Not sure what i'm talking about? Okay. Most of my projects are gonna be on Yanfly Engine Ace. That's 107 bloody scripts to add in. Have fun doing that, and nothing else for a long while.
I understand the batch adding. More because most people here use a lot of premade code (that's the spirit behind RPG Maker! or so it seems). But if you know you have this entire set of scripts you ALWAYS use, why don't you make a template instead of adding them every time? Create a project somewhere else, add all Yanfly/Yami/whoever else scripts you love to death, save it. And then every time you want to start a new project, copy and paste that "blank" project, remove the things you think you're not gonna need (or not). And voilà.
You know, deleting scripts is easier than adding them. xD. Delete button is so convenient and reliable.
