				ebook-viewer when running from source
			 
			
			
			When running from source, ebook-viewer takes 5-6 seconds to open a book from the Calibre library. This doesn't occur when I'm running stable. Is this to be expected?

			No, I am currently focused on the Qt 6 betas, if you want to use a release, use those, they include all changes in master.

			Are there any database changes that mean I can't downgrade back to 5 if I need to?

	  I'll grab the portable version and then copy my config into the settings folder.

			While running from source, I thought it might make things faster if I temporarily switched off the internal viewer for ePub while the system default was C:\Program Files\Calibre2\ebook-viewer.exe. However, there was still a delay. Is it still doing the compilation?
