See possible workaround below.
I’ve voted, and also made a strong plea here:
If you’re in dire need of a possible workaround until/if Tags return to My Tasks, consider:
The ability to multi-home a task (add it to multiple projects) can be seen as an alternative to tagging. And there is a column in the new My Tasks for projects.
If you have tags for priorities P1, P2, P3, you could create three projects P1, P2, P3 and multi-home tasks to one of them.
Show the tags view (type P1 in search and click the tag in the popup menu) and multi-select tasks there (in batches of 50) to quickly add them all to the appropriate, corresponding project with the widget at the bottom of the screen. It will even offer to create the project if it doesn’t exist (though it’s a mystery how/why it automatically chooses which team to put that in!).
I’m not advocating this instead of bringing the lost Tags feature in My Tasks back, I’m just offering a workaround for those that might find it helpful.
Hope that might help some,
Larry
