[FR] Move tab to next/previous group

[islisis]

I have keyboard shortcuts assigned to moving tabs to a set groups, but don't have a keyboard command to move it to other groups in-between.

A feature to move tabs up/down the group order would be useful to me as I order my groups according to different categories/purposes, with related groups next to each other.

It would be great to have keyboard shortcuts to achieve this by moving the current tab to the next/previous group, just like there are keyboard shortcuts to view the next/previous group.
