Tonight I released Keiki Usage Meter Version 3.2.1. This release was prompted by Optus changing some things on their end that stopped the Optus Broadband (Legacy) plugin from working. There are some changes to the way tooltips, buttons, group boxes, combo boxes, radio buttons and check boxes are rendered, but nothing particularly noteworthy.
I also published some (sparse) documentation on developing plugins. I’d be happy to publish third-party plugins on my website at some stage.
