While using pnotepad for over a year now I got a small list together of things I missed or din't work correctly, I hope it helps, and i didn't do/ask stupid things:
1. UTF-16 support
2. code folding doesn't work with assembler scheme (PROC->ENDP, MACRO->ENDM, STRUC->ENDS)
3. pnotepad doesn't apply schemes to self added extensions ex: dsm added to open with asm scheme -> doesn't work
4. when switching tabs, tab forgets position in file
5. permanent line-numbering option
6. will there be a portable version for a usb stick?
Anyways, it is still the best notepad out there, so keep up the good work.
