[REQUEST] Ability to filter out owned PRs and Issues

[arielj]

Branch/Commit:

Main branch.

Describe the feature:

As a User
I want to see a checkbox at the top of each table with a label Hide owned ...
And when I check that
I want to filter out the PRs or Issues that I have created

We could store the status of those checkboxes in the cookies.

Problem:

Currently, if we create many PRs or many Issues that takes a long time to get done (mainly happening with issues), the table can get too big and assigned items can get lost between all the owned items.

It would be useful to check/uncheck that to filter the extra items.

I will abide by the code of conduct
