 ## `C` cosmetic, `F` functional, `P` performance, `B` bug fix
 
+* `F` auto unit conversion in/out of fields so display = pref. but always store mm?
 * `F` implement an in-app bug reporting system
 * `F` extend mesh object to store raw + annotations (rot,scale,pos)
 *     share raw data w/ dups, encode/decode
