In Doit, the tasks' tags are not visible in the list. You have to open the task to see them, or you can try filtering to see which tasks are affected by which tag.

But I am the nervous type :-)
I like to double-check my tagging during my reviews. Most apps have the tags visible and that makes it easy to just ocularly scan the list.

How do the rest of you do this in Doit?

I tried to suggest as a feature that tags be made visible, but did not get any encouraging answer. http://help.doit.im/topics/1448
