Required, but missing features for Theme installation/management in Edge

#1

Create an Internal Edge page for themes, like this: edge://themes/

#2

Add a button with the title "Themes" to the ellipsis menu, possibly below "Extensions" button

#3

in edge://themes/ create a section to see our installed themes, so we can view them, activate any of the installed themes and delete any of the installed themes. also show where the theme originates from (i.e which webstore it was installed from or in case of manual install using .CRX file, show the Theme ID only).

something like this which is from Firefox

#4

this is a related bug: so in after clicking "Remove" in here:

the theme doesn't seem to be uninstalled, that button only deactivates the theme. because after removing the theme and going to the theme's page on Chrome web store, I see this:

when I click on "Enable this Item", the theme activates again without redownload.

this is another reason why suggestions #1 to #3 are important.

The same problem happens when using Themes on Microsoft Edge Addons Store

As you can see the Edge addons store says the Theme is "Disabled" and Not "removed".

so there must be some sort of hidden feature for this already in place, only the UI elements are missing to manage it.
