Currently, I use Atlassian JIRA on my job at Kayako – I use Redmine for my personal projects. And still I like Redmine more! But, what I like in JIRA is sequent numbers plus the project key in issue IDs. There are many benefits to such issue numbers, some of them are: a) you easily see how many issues the project has, b) it’s much easier to remember issue IDs (even if numbers are four-digit – not sure why, maybe because you follow numbers increasing), c) you always know, which project the issue is for. These are no way critical benefits for me, but one day I got interested – how the similar can be implemented for Redmine. So, I started to experiment… And eventually here goes the result of the experiment – the ISSUE-id plugin for Redmine!
