Apache OpenOffice (AOO) Bugzilla – Issue 112390
allow color adjustment for protected sheets (value highlighting)
Last modified: 2014-01-10 12:05:49 UTC
after a sheet is protected, background turns into dark grey if value highlighting is enabled, for ergonimic reasons it should be possible to adjust the color, for example get a lighter grey. a lot of users complain about the bad contrast (e.g. the dark green formular results with grey background). a good example is the new selection transparancy adjustment in "tools – options – view" where users can adjust the transparency level to their needs.

Useful enhancement.
