A GUI designer, similar to Kayls' QT system.
Also, an "Easy Script Designer", in a "flowchart format"
So like there are two rows in the page, client and server seperated by a thin line (red and blue backgrounds)
Then you can Drag and drop "Command handler" from the list to either side. You double click the item to change the command (the edit is selected by default), right click it and press Change variable name (to change it)
You can attach various actions to the object (handler) and do some stuff with it.
If you create a GUI using the GUI designer, you can drag it to the page (client only ofc) and do some basic actions.
It's a very long shot, but whatever, It's not bad that I give ideas, right?
