I realize there is a ticket open for XSLT 2.0 support.
For me the most useful feature would be code navigation between files by CTRL+Click on template names.
This is already possible for XSLT 1.0.
Can this limited functionality make it into Maia release ?
Some support for xslt 2.0 in Maia is better than no support, or full support in a few years.
I currently use Stylus Enterprise which is a great tool, but for daily editing I prefer to use IJ.
