could this be added (as an extra option) in next update?
It has been since the protracker days that I’ve last used hex, so I lost the ability to think that way 
, but does it really help much? Only from a to f (10 to 15) you’d have a change and how many times do you edit-step in that range? Probably just me.
What about DSP parameters which refer to Lines, such as the Delay or LFO devices?
Think I made a similar suggestion a long time ago, before I stopped using LPB of 8 or 16 so much in favour of 12 or 24 and found going back to decimal easier on my brain…
I guess if you’re more comfortable in thinking hex than decimal than go for it! For me it would be confusing to set an lfo to a frequency of C even if the numbering of pattern-lines is in hex, after 3 iterations I wouldn’t quickly know which line I’m at in the pattern, especially if the lfo gets triggered with a reset somewhere other than the first line, but I suck at math 
reading this stuff about people who are not using hex makes me wonder if i will be more comfortable without hex as well… never tried. i’m scared.
