Like I said, it's a minor thing, being able to export/import the actual data is itself a fantastic feature. I very much look forward to having my character printed out on this new sheet at my next D&D session this weekend
Great to hear! Have fun this weekend (and make the other players jealous

)!
What could be an meaningful update would be to look at the 'companion' sheet (last 2 sheets). It's barely been touched since... forever.(...)
There's probably other stuff as well, but I don't use those pages so my feedback is limited.
>> At the very least, the HP section of the companion could be made to mirror the layout used on page 1, with the Max/Current in the 'main' box, and a 'Temp/Wounds' in the other box.
Great idea! Done in the new version.
>> Make the 'Heal' button correctly update the hit dice 'used' to reduce by a number equal to half the hit dice.
Another good addition, did this as well.
>> Then maybe give companions an ammo section.
I think ammo is not something companions will use that often as they will most likely be a familiar or animal and not a humanoid with gear and ranged weapons. And even if it is the latter, it will most likely almost never see combat because 5e really tries to limit the amount of creatures every player has to control (or at least the amount of options for those creatures).
>> Convert one of the notes on page 5 to be an inventory.
Same argument as for the ammo, but here I also want to say that there is enough place to put the basics (armor, weapon, etc) down in the features/annotations section. If the companion is so complex that it needs a whole inventory section, it might be better to just give it its own character sheet.
>> Have a place to record the proficiency bonus.
Again, this would mean it is a very complex companion, possibly with character levels and whatnot. I would definitely recommend using a separate character sheet for such a companion instead of trying to fit it into a limited companion section.
With these additions it is time for a new version:
Character Sheet/Generator v8.6 (30-9-2015) has the following changelog:
- Changed the welcome pop-up to include a reference to the changelog and pointers on what features not to miss (as per the suggestions of Headbomb and Astromath)
- Added a maximum HP to the Hit Points tooltip
- Updated the companion Health section to look and work the same as on the 1st page (i.e. Current Max HP, Temporary HP, tooltip with hp, heal button for half HD) (as per the suggestions of Headbomb)
