At the moment I am tracking work units for when I actually work, so Hobbies, Chores, other personal things, are not being tracked.
The reason why I don't track personal stuff, is if I do track them (which I have done at the very beginning) and export my work units, all of them are exported, but I only need specific ones.
I was not able to see an option, where I can select the specific work units I want to export. So this is a feature request to add it.
It could be as checkboxes, where I select the Units I want to export. Similar to this:

WorkingHours version: 2.7.1.0
OS + version: Windows 10
