Fix the “default” tool / drawing colour settings.

Checking the “use as default colour” option (or however it’s worded) on a tool or object (ie fib tool or horizontal line) just doesn’t work. 
 

As soon as you use another colour for another object, it then sets that as the colour for the next thing you pull up. 
 

It’s so frustrating and it’s been like this for years now and still not sorted. If you use lightly coloured, opaque rectangles like I do all the time to mark zones, and fibs (which u can’t make out in the opaque grey!), it’s a bloody nightmare having to keep changing the colour all the time. “Set as default colour for xxx” should set the default colour for that particular tool/object, just as the option suggests it will.
