Hi timo . As you are about to release a new behaviour for hiding tasks I wanted to ask you whether there would be an easy way to implement a feature for hiding individual working hours as well, much like gcapotorto suggested. Your suggestion to use tags would work of course. It just means that I'd have to constantly apply a filter to hide those units. This limits my abilities to use the filter for other stuff.
I used Qlaqs for some time, which allows me to batch-select certain sessions (pretty much like suggested here) to do lots of different stuff with them including adding them to the "archive". If you want to see the hidden working units, you can activate the option to "Show archived tasks" in the filter-menu. A feature like that would be amazing as I could just hide working units, that I don’t need anymore while at the same time I’d be given the opportunity to use the whole possibilities of the filter for "unhidden" units.
