Add keybinding customization to newtab

[CouleeApps]

What is the feature you'd like to have? I set cmd+1 / cmd+2 / etc to open specific sidebar widgets (CLion user detected) and now the New Tab page lies when it says I can use cmd+1 to open the first file. I looked for that keybinding in the keybindings menu but it is not there (it is hardcoded in Launchpad::keyPressEvent). I want the ability to rebind those keys

Is your feature request related to a problem? I want to reopen previous files quickly

Are any alternative solutions acceptable? The previous newtab page used just straight 1 / 2 / 3 / etc for hotkeys, that would work too
