I'm still insisting on using redmine at our Drupal shop after 15 years instead of switching to Jira (fight me!). We also tried using trac back in 2007 but realized we needed multi project. Every few months/years I keep looking for a more modern alternative (open source or extensible SaaS) but never find anything worth trying beyond adding a few "test" issues. (So far: Jira, Clickup, Linear, Monday, Asana)

We even taught several of our devs Ruby on Rails over the years to write various plugins. One of them quit to go try and work at Shopify, no less!

In the spirit of making my comments useful, here are the custom redmine plugins we built and maintain for ourselves:

https://github.com/evolvingweb/redmine_default_members - This plugin allows to create default members on project creation, based on Redmine groups.

https://github.com/evolvingweb/redmine_slack - This plugin allows to send notifications from your Redmine installation to Slack.

https://github.com/evolvingweb/redmine_atjs
Redmine plugin that integrates At.js library to enable auto-completion based on issue titles, while editing wiki and issue pages.

https://github.com/evolvingweb/redmine_evolvingweb_extension... - bunch of random UX hacks we can’t live without. Some aren’t documented in the readme, including ability to search archived projects, and adding extra fields to redmine timesheet reports like Custom Fields on users.

https://github.com/evolvingweb/redmine_paste_text/ - integrates puppypaste.com functionality into Textile “wysiwyg” editor, allowing pasting HTML content (eg from emails) that gets automatically convert to textile

You can uncheck the box to not change the assignee, otherwise, it will be assigned to this user.
