Known Bugs/Issues
==================
1. Group IDs always increment and never decrement after closing a group so if you've been using PTG for a while, I'm sure your IDs will be very high. I'll be fixing that soon, should be an easy fix.
1. I'm sure many translations broke with the new plural rules. Please take a look at the bottom of [this page](https://github.com/projectdelphai/panorama-tab-groups/blob/master/CONTRIBUTION.md#translations) to learn how to add plural rules to fix any broken translations.

I know things have been pretty quiet around. I've been doing a lot of side-projects due to a new job to keep learning. Just got my revised environment up and running so while it isn't very pretty, I am able to merge pull request and do quick changes now. Should hopefully be back on track now :) Sorry for the wait!

Thanks for waiting and supporting this project :) As always, suggestions are welcome [here](https://github.com/projectdelphai/panorama-tab-groups/issues). We're especially looking for translations so please help if you can! If you're not sure how exactly to submit a pull request, you can just translate every message line [here](https://github.com/projectdelphai/panorama-tab-groups/blob/master/src/_locales/en/messages.json) and drop it in an issue and I'll put it in the code.
