I've only been using GMEdit for a few days, but already it's become an indispensable tool. Going back to the standard Gamemaker Code Editor feels like trying to code with caveman tools again.

Unfortunately, been forced to do that due to GML 2.3 Beta changing the .yy definition of objects, which is preventing GMEdit from saving object files. I believe it's because spriteId is now a JSON object instead of an ID string, and variables are identified by the key "name" instead of "varName". 

Hopefully this can be addressed soon, just wanted to bring the the dev's attention!
