I've been away to post updates on this thread.
Here's changes log from 0.8.2 to 0.8.4:
Fixed: Script can handle PSD file's layers properly.
Added 'Not render immediately' option to 'Proxy Rendering Setup'. If this option is checked, render command won't execute at once and just save project file.
AEP file is saved in folder;
Added 'Save As Default' function to 'Proxy Rendering Setup'. Now you can save your setting of Output Module, Multiprocessing and Sound option as default setting. Preference file will be saved in 'ScriptUI Panels' folder.
