Where are the tags in Goplan?

When creating a task, a ticket, a page, anything it's great to have tags available. The Lighthouse application has a great way of dealing with tags you might look at.

It works very well the way you're able to just click your recently added tags on the fly, and how you're able to use them as categories.

Say you're dealing with a problem with png and javascript you could tag it with relevant keywords instead of hiding it under a "I can't even find a fitting name" category?

Plus when creating a new task/ticket (whatever) a list of your most used tags should be readily available for clicking.

Really, it works wonders in the Lighthouse app.

Thanks :-)
