Installing Packs can/should be easier

[chimp_spanner]

From the top level pack/thumbnail view we can preview, but to install the pack you need to click into it (thereby losing your place in your chosen category). And to uninstall it you have to go to manage packs. I think it'd be cool if when browsing packs the thumbnail works like so;

(+) to install
(✓) when installed
(x) when hovering over (✓) to uninstall

Also "Install All" should be an option somewhere. Even if it's in a sub menu or comes with a warning that it may take up a lot of space.
