@tprouvot I figured if this works well(currently unfinished), I might include or combine it with #1058

[Garywoo]

I would love to be able to open the Show All Data page directly with one keyboard shortcut that could be configured in the extension keyboard shortcuts settings, as described in #633. Does this PR enable this?

[tprouvot]

@Garywoo in the idea yes, but I need to see with @RubenHalman if it can be done without replicating the logic from background js and popup into button.js

[RubenHalman]

@Garywoo Closing in favour of #1192, rebased onto latest releaseCandidate and addressing the feedback to avoid duplicating logic from background.js/popup.js into button.js.
