restore workspace with lazy loading tabs

[lazymonkey2]

Hello, I'm using Workspaces 0.6 with the option to close tabs.
When I restore a workspace I noticed that all tabs are loaded at the same time.
I'd prefer that only the current tab would be loaded, and other tabs should be loaded only when I click on them.

I have installed another extension that claims to do exactly that: it's called sloth and you can find it here:
https://chrome.google.com/webstore/detail/sloth/filkeckmpdjogddcamkafnekhgfaehkc
It seems to work when I start chrome and it restores the previous session, but when I switch workspaces it doesn't work.
Can you implement a mechanism similar to sloth in your extension?
Thanks.

I think it's better to use TabSusbender instead of making this tiny extension more complicated.
