Feature Request: Add tags

[DeflateAwning]

I want to be able to add tags like "location:office" or "location:home" to tag where I worked from for each time tracking entry. Is that a feature you're able to consider adding? The tags would be arbitrary, of course

Thanks for the suggestion! I think I would consider such a feature if it integrates well with current file format and the application, overall. If we can add tags to activities, it should also be possible to filter lists and reports by tags. We should also have a command to list all currently used tags
