I have been playing around with various colour themes to brighten up the various forms and views, without success.
Out of interest Chris, what is the theme or colour scheme you used for the screenshots used in the help?
I'd like to attach a sample, but can't. If you open the help:-
Using doogiePIM > Main Sections > Tasks > Managing Tasks, and scroll down to the 2nd main screenshot.
The Add/Edit Task screenshot has a green header, bluey grey background, with bright blue buttons...
