Looks good ! Going to merge this now and I will try to release the update today if possible.
Thank you !

Thanks for merging, I'm in the middle of a lol game but I saw that I messed up with this PR because forgot to correct an if statement grrr.
In the tag page-list the if statement needs to be if={opts.tab.active == "blitzgg" || opts.tab.active "opgg"} and not f={opts.tab.active == "blitzgg" || "opgg"} maybe you could change it before you release it. Because otherwise the item set button will be shown on every page which is miss leading.

Yep, I've already fixed that in local, just need to push it with the version bump, dont worry ^^
Just currently trying to figure out why I seem to have some performance issues with that build, but that might be something non-fixable in the short term.

• I need to temporarily disable MetaSRC due to not working and presumably leaking memory due to a redirect loop.

Okay actually, we need to wait with the release since somewhere within the op.gg plugin we seem to use somewhere around 700MB to load pages (at least for Lux, havent checked other champions), so we currently spike to around 1GB ram usage. Im going to try to take a look whats happening there, but that might take a bit.
Edit: Doesn't specifically seem to trigger on the op.gg plugin, but rather when switching away from a page with the builds modal, so I have 0 clue what causes it so far. (seems to be around 700MB each time when swapping away from any page with an item set)

Moved the problem to #118 so its easier to find.
