A company that brings start-ups and other Agile software development projects into life, following Agile principles rigorously, trying to follow Scrum framework as much as we can, using JIRA and its plugins.
At one point we realized that we just needed additional tools (such as Excel) to make our issue handling process easier, smoother, so we made a plugin for ourselves to replace them and now we are bringing it to you to see if you like it as much as we do.
