UIBooster help?

Hello, first : just to know if anyone use it !

second : I’d like to use a Form with a canva element, I don’t know how to modify the windows width and to have the content when it’s closed (I don’t really understand the explanations on uibooster github) !


P.S. I need a very little text editor to write markdown and html code to make an application to make static web sites. I’ve already made one with Processing where the content is on a json file. It takes the json file and some html template files to make the site web pages…
