[Idea] Make Zen less memory hogging when using pinned and essential tabs together

I am using Zen for a few month now and i noticed that Zen use a lot of memory with all the pinned and essential tabs.

I get the idea of essential and pinned tabs where essential are globally accessed like all workspace can have the same essential with different pinned tabs. But since Zen also support container-specific-essentials, I think pinned tab should really have to innovate.

On start up, all pinned tabs and essential are appeared in about:process at idle state (indicate they are unloaded). If i kill a process of a pinned in about:process, it doesn't make a different beside reduce memory.

Here are some thoughts that i think will make Zen better in term of memory:

So maybe we should treated the pinned tab like a quick access bookmark.

Or

Make the pinned tab not load on startup (no process for pinned tabs on startup, only process for essential tabs)

Or

Make Bookmark toolbar item can display vertically in sidebar

i highly agree with this, i think the last one will be bad cuz the side bar will have too much going on so the better idea is making the essential tabs unloaded until u open them

I can see in the latest update on stable branch, this has been implemented i guess.
I have a 3 workspaces with a bunch of pinned and essential tabs in each (could be 20 or more essential and pinned tab in total).
And it only takes like 4-500mb when start up (i've tested it without any mod) and no other process appeared in the process manager other than the new tab process.

The dev team really listen to their users and trying their best. Hats off to them.
