@srishakatux:
On https://wikimedia.biterg.io/app/kibana#/dashboard/Gerrit-Backlog we already have a widget/visualization called gerrit_backlog_table listing and linking unmerged patchsets in Gerrit.
And on https://wikimedia.biterg.io/app/kibana#/dashboard/Gerrit-Timing we already have a widget/visualization gerrit_all_changesets listing and linking all patchsets in Gerrit.

I now added both those widgets (for testing) on https://wikimedia.biterg.io/app/kibana#/dashboard/C_Gerrit_Demo .
Once you click on the name of an author (to apply a filter view), those new two widgets will list all unmerged patches resp. all patches by that author.
Could that work for us? (If your screen is smaller, you can change the size of a widget by dragging its corner.)

If this turns out to be useful and we want to keep this, I'd need to figure out how to not get my custom change overwritten when upstream deploys the next update.

(Note to myself / admins on wikimedia.biterg.io: To add such widgets to an existing dashboard, go to https://wikimedia.biterg.io/edit/app/kibana#/dashboard/C_Gerrit_Demo (in this case), click "Add" in the upper corner, enter the name of the visualization in the search dialog, select it, and click "Save" to overwrite the default version.)
