Looking great so far! Things that I love: Equipment tab is awesome, really nice layout, great information displayed. Simple rework of the skills check boxes, simple thing, but nice presentation. Roll tool-tips for skill checks, providing tags for the bonuses is so helpful! New weapon section is very versatile, eliminates the need to use class actions for many things (spells like hex, sneak attack, etc...) Possible Improvements: Rename "Class" tab to possibly "Character" (or whatever else makes sense), take the Appearance, Vision, and Movement sections from the Configuration tab and move them to the top of the new "Character" tab. Keep the class levels on the "Character Tab". Not sure that I personally find the proficiencies and languages useful on the "Core" tab, maybe it is better being moved to the proposed "Character Tab"? While the custom skills slider is nice looking, maybe it would be better as a simple toggle. This may allow you room to put the Jack of all Trades toggle inside the skills box where it makes more sense? Setting classes does add appropriate HD to the Core tab's Hit Dice box, however removing classes does not remove these. So once they are there, it seems there is no way to remove them. Would it be possible to add a total weight to the Inventory section of the Core tab? It would be even more awesome if you could change the color of the text or the background to red if they are encumbered. In the Inventory section of the Core tab, would it be possible to "click" on the item and have it output the item and description to chat (via roll template)? This would allow you to add say healing potions to inventory, then include the roll in the description and have it output this information. In several places there are no "arrows" for the clickers of the world (Core: Spell Slots, Hit Dice, Coins; Spells: Spell Slots; Equipment: Individual armor bonus; Config: Ability bonuses, Skill bonuses) I would love to see all roll tool tips show the tags if possible, super helpful if there is a need to troubleshoot a roll. I know that much of this is a WIP so if it is still things being worked on, then feel free to ignore anything above.
