I am using the 5e css to create a Rules Cyclopaedia compatible sheet, I have not merged it yet (I still have a few things to finish before it is complete for the PCs). You can take a look at it here <a href="https://app.roll20dev.net/join/35785/vwf07A" rel="nofollow">https://app.roll20dev.net/join/35785/vwf07A</a> and feedback is most welcome. I will put up a few empty sheets to play with. Or the source on my fork here <a href="https://github.com/allenmaher/roll20-character-she" rel="nofollow">https://github.com/allenmaher/roll20-character-she</a>... Right now most of the PC fields are working including options like general skills, weapon mastery support and so on. I am planning a big inventory overhaul from the 5e sheet so that will take a few days/weeks. It supports the 5e style spell book (reversioned for BECM of course) and 5e style roll templates. In progress right now are the DM only rolls (turning, thief abilities, elf, halfling and dwarf abilities) which will probably just whisper to the DM a request to roll with the appropriate score (otherwise the player sees the roll). Two distant features I need feedback on are what should the NPC sheet look like (what do you want the most in it) and whether or not you want a tipple toggle from player sheet to npc sheet to force sheet for mass combat. What won't ever make it into the sheet by my hands (open licence so code if you want to) is domminions, and strongholds. Frankly the handouts work well enough for those.
