I’m happy to share my first plugin: “Format Dutch license plate” !
It formats any input (upper/lowercase with/without dashes) of a dutch vehicle license plate to a more friendly and readable format: all uppercase and with dashes at the right breaks.
I made it for myself, but thought I’d share it here, knowing that 99.99% will never use this, but maybe it inspires you to build a similar plugin 
If you do have any questions about this plugin, contact me!
