I'm new, so this may be old hat...but I looked around and couldn't figure it out.
Is there a way to have multiple independent tags? For example, if I use TagA and TagB from time to time; can I enter both "TagA, TabB" in the tag field of a task and subsequently sort by Tags and have the task listed twice...once under TagA and again under TagB?
You can add multiple tags like you are suggesting, and then you can see the task listed under each tag when you are in the tag view and click on the tabs at the top of the page. However, if you are looking at a list and sort by tag, the task will only appear once under the combined tag heading. You can try it out and see what I mean.
