+1 for this. Also, the dialog's columns need better default widths (too
thin now), and a little text about what the dialog is about would go a long
way for new users.

Yes, very annoying. Maybe there is a better way to indicate to the user
that transformations need to be addressed, even after a default one is
applied and the layer loaded?

For me, this is the most salient reason.

Agreed. This is already the case with the CRS dialog, which routinely
mystifies some new users, even is it is completely necessary to basic GIS
