A couple of months ago I'd build a quite handy extension that makes life a bit easier during PCB layout process.
Finally found some spare time to open source it - detailed description and installation instructions can be found here:

Briefly\, it is a "context menu" like thing with specific design that consolidates all the alignment actions and can be triggered by a single key shortcut \- \`A\`:

It works both for `PCB` and `Schematic` documents, but for schematics the value is quite low though:

Also, this extension supports a special mode triggered by another `SHIFT+A` shortcut to set postion of prefixes of selected components:

Hope it might become useful for other users. Feel free to send any feedback in this thread or using `issues` in the repo. I'm especially curious whether the extension works on Windows and various browsers, since I had a chance to test it on `macOS / Chrome` pair only.
