Not that it matters in terms of miRNA function, but I think it would be nice if the mirtrons were distinguished from the traditional miRNAs in some way. It might help when looking at Dicer knockouts to figure out what miRNAs may still be around.

I totally agree with that, and would love miRBase to read these comments and do something about it….
