The sheet for both Roll20 and on Github, do not have the updated 2e professions. So I added them in, and I also added a section for the Martial Arts (below the weapons skills in their own Martial Arts Skills section) that one can take as a warrior monk, monk, and a shape shifter. I am also going to add the skill called adrenal defense down below body development. The sheet is a bit buggy. Both the one you can get in Roll20, and the one you can get from github, do not fill out some of the check boxes correctly, but the final calculations are correct somehow. As for instance, various professions give you a 1,2,3 in various skills, per lvl. but if you go an give your character levels, that bonus does not reflect correctly. The final calculation does, but not in the visual display along side the check boxes, if that makes sense. This is very apparent when you go over lvl 10 as well. I am also thinking of adding a drop-down with each race/culture that you can select that then would auto fill some things, sort of like how the professions work. I then may work on the secondary professions, giving you the ability to pick from a list that auto-fills as the profession list does. Then maybe the spell lists. Just messing with the sheet to fit my needs. As for directly editing the Roll20 sheet, I have no idea how to go about doing that, I can't find the code. So I just pulled the html and css from Github and placed it into the custom sheet windows along with my code changes for my "new" MERP character sheet.
