About C20

C20 is a browser extension for Roll20 that adds a number of quality of life improvements to the D&D 5e 2014 character sheet and game. Overall Features - Journal management for players (hide, filter, sort, and folder management) - Custom compendium - Marker menu with labels next to each icon D&D 5e 2014 Character Sheet Features - Conditions tracking, similar to exhaustion tracking but broader. - Defense section to track resistance, immunity, and vulnerability. - Added markdown support for large text areas. (bold, italic, list, tables, headers) - Inventory tweaks that allow dividers, different colors for magical items, and advanced item editor - Spell table layout and filter - Sheet settings has area to turn features on or off as desired This is just a fun side project that started when a friend wished they could organize their journal. And then I kept just adding different tweaks here and there. I feel like the goal of this isn't to overhaul the existing sheet, but to clean up some of the rough edges. All data related to new features that cannot be stored in roll20 are kept and stored locally. This includes custom compendium data, conditions, defenses, and C20 settings. If you wish to backup or transfer this data to another computer, there is an import/export option in the game settings.
