I use Wavelab everyday. It is my go to DAW

As discussed earlier, there is an option to stay away from the WL’s file selector by switching to system default.

Yes, the right click - snap cursor, scroll to etc. is gone, however, scroll to can still be achieved using Shift + Home and Shift + End.

When you are using File Browser, there is an Add to Favorite feature. Here you can add your default user or any other folder.

I think there has to be an option for Default User’s Quick Access Foldes auto added to WL or the Default User Folder as Default to the left.
