I've now published a small alpha version of it.
DownloadHere are some infos you should know:
You can double-click on a panel and can write the "on_click" function (i've oriented this at c++ editors)
You can also manage your functions, that means different panels could have the same functions, so you can easier edit them. You can also remove a function or a panel by pressing "Del" while it is selected.
You can duplicate a panel by pressing CTRL+V
Move panels by using the mouse and drag/drop them or use arrow keys.
The tool does automatically make backups of your current project files.
Because it's just an alpha version I've disabled script export so far.
Please tell me what you like/don't like at the functions.
If you get problems, tell me them too
