[TxMt Plugins] Re: tracking the filename of the currently selected tab

Yes, it doesn't quite do what I want... but thanks to both of you for pointing it out.  In particular, WebPreview doesn't track the current file, as far as I know.  I would also prefer it if the preview window were not separate but rather integrated into the Project editing window, probably with a slider to adjust the real estate used for editing / viewing the transformed version.

Great, that's exactly what I was looking for!
