Javascript Userscript for browsers - allows creation of a list of columns based on labels in a gitlab issue board.
Until Gitlab supports portability of Issue Board settings (better/at all) here's a simple hack in Userscripts style - in your browser use an extension like TamperMonkey to use it.
You will need to customise the script to your needs - you'll need to set up your labels (the string and the ID numbers). There's no GUI or UX component - to kick things off when you are set up, you need to use the console in your web browser of choice. I've only tested this with Firefox for my own needs - sorry, that's really basic testing and I should (and do) know better... but it was a quick hack to get things to work quickly.
Maybe someone would like to collaborate and fix it / tidy it up / make it cool. Until Gitlab themselves gives us a proper implementation.
It may, obviouly, break when they update the document object on the issue board pages - so it'll need nursing. :-)
