Typing in a title and then manually adding tags afterwards is quite disruptive to my workflow. It would be highly productive to have the title box be able to dynamically pick up tags using keywords.
Example Title of what I would type for a new task that I'm typing in:
"Go buy milk :tag Safeway :tag @Alyssa"
The title when then show:
"Go buy milk" and the task would have the tags Safeway and @Alyssa
During the process of typing in the title bar, the bar would find the key word :tag and dynamically populate a short list of known tags with the first few characters typed after. You can either select from the list using tab (and arrow keys if needed) or create a new tag by finishing typing in what you want. The tags typed would not show up in the title. Even better is the software wouldn't wait for you to finish typing in more text after each completed tag, it would immediately remove that keyword and tag and put it in the tags of the task.
I know a competing product which does this. It would be great to see it here too.
