Could JIRA be faster, easier, etc...? Sure. But, I have tried many products to run agile/scrum teams and haven't found anything that gives the flexibility and options that JIRA has.
The "better Jira" that I dream of is simply Jira but faster and with a better UI, I don't have issues with the underlying process
- the keyboard hotkeys aren't customisable, and often fire when I'm using alt+numbers to switch tabs, so when I come back to the Jira tab it's on some report page I don't care about
- sometimes the content won't render when switching pages, requiring a full refresh. It's difficult to tell whether it's just being slow to load, or it's gotten itself stuck. Sometimes I sit there for a few seconds like an idiot until I remember to hit refresh
- there's pretty poor support for ticket templates as far as I can tell. My company's method uses a confluence page with a table with the templates, then uses the bulk "create Jira ticket" option. But this edits the wiki page for some reason, which you need to revert. They're probably expecting you to duplicate a whole template page before generating, but the editing part could be an option in the generator wizard. With this method there's no way to go back and amend the auto-generated tickets' titles and descriptions etc. You're stuck with manually editing all of them along with the template. Surely templates are a common enough use case that warrant a dedicated workflow?
