@version        1.0.8
@description    `Removes lots of vertical whitespace on the subscriptions list view. Will break the grid view and removes the button to change views, <b>make sure you have the list view selected before activating</b>.
Changelog:
1.0.1 - Make fifth element in list smaller, as it is assumed to be a shorts shelf, but don't remove it entirely, in case it is not.
1.0.2 - shorts shelf moved to fourth position for me, changed the code accordingly.
1.0.3 - shorts shelf has been removed for me, commenting out the no longer relevant rule.
1.0.4 - the shorts shelf is back :/
1.0.5 - and now it moved position again...
1.0.6 - youtube just hates me
1.0.7 - maybe it's time to consider just not using it anymore
1.0.8 - -.-`
