This extension allows adding formatted-text annotations to any "misc" numeric field on the character sheet.

I find over time I often will forget where the values I entered for "misc" actually came from, so this allows one to enter a description, or a link to a section of the rules, etc.

Any "misc" field on the character sheet will have a small icon designation in the lower right corner showing it can have a note attached.  If a note already exists, the icon will have a slight blueish tint.   CTRL-clink on the field to bring up the note editor.  The note supports the standard FGU formatted text (i.e. normal, heading, chat, list, link, etc.)  After entering the formatted text, hovering over the numeric field will cause a tooltip to appear with a plain text version of the annotation.

I tested this with PFRPG 1E, but I think it should work with any ruleset as it is adding behavior to the number field from the CoreRPG.

Please refer to the forum thread for more details and sample screenshots.
