What is the problem you are facing using Phabricator? Mostly, a page like this seems like a band-aid solution to some other core issue. What is that problem?

https://secure.phabricator.com/book/phabcontrib/article/feature_requests/

User is subscribed to 50 tasks.
User feels he is no longer interested in about 25 of them.
He just wants to unsubscribe to 25 of them without messing anything else (email preferences) up.

You can already do this at least in Maniphest with the Batch Task Editor.

Maniphest > Advanced Search > Subscribers > Batch Edit > Remove CCs

Or what I prefer if I receive an email for a task I no longer am interested in is just reply to that email with !unsubscribe and you'll be removed.

OK but the user sees in the mail

EMAIL PREFERENCES

https://secure.phabricator.com/settings/panel/emailpreferences/

so perhaps a simple 'unsubscribe to this task' link should be added to emails.

We are discussing making that simpler, that is instead of a link to email preferences, it'll be a link to "i don't want this mail" and it will let you opt of whatever reasons you received it. That is T9161.

I presume the Batch Task Editor resolves your specific request?

This is 100 times harder than a simple left panel menu item "Manage subscriptions" which leads to a simple list of ones subscriptions with checkboxes...

If you're anticipating needing to manage your subscriptions often, you can save the query and call it "Manage Subscriptions". It will appear on the left in Maniphest.

Wait! All https://secure.phabricator.com/maniphest/query/subscribed/ needs are little subscribed checkboxes next to each item.

We can't justify pursing such changes there. Specifically, there is already a means to solve the problem as you've stated it today. Building a customized view would not solve any new problems other than being perhaps slightly easier. As this is a feature that is rarely, if ever, needed or used, its not worth upstream time resolving. I understand its not perfect for you, but we have a very small team and only spend time building things that impact the most installs.

Checkboxes in general should probably be pursued for "batch editing" anyways, since it's more mobile friendly. We'll definitely consider that.
