I decided to open source Treenga issue tracking system I worked on the last year. It was mainly created to provide an easier way to create task descriptions in "full-page" mode, where images will be treated as first-class citizens, and provide a way to manage hundreds of tasks. Something like a hybrid of Dropbox Paper and Github Issues. Treenga has a hierarchical tag structure, so you can create a structure like
Departments
-- Marketing
-- Product
-- Development
Importance
-- High
-- Medium
-- Low
etc.
Now I want to open source it, so you can install it on your own server and use it for free under MIT license. It is done by using Laravel (PHP) and Vue.js and required about a 1 developer/year to build, mainly because of several changes in the project concept (I suppose it would be about 30% faster without that changes).
