- The list is very long, its hard to find the columns you are after (it took me a while just to find the issue key column), perhaps you could add a few key ones at the top of the list as well (e.g Key and Name).
- There is no horizontal ordering available, it only does it alphabetically, so there is no way to achieve "the default plus one extra column". This could be helped by just ensuring that if they select the issue key, it will get put on the leftmost column no matter what.
- Gadget width was an interesting hurdle. I added a bunch of columns and they just got hidden off the side in such a way that i didn't even realise that there was more to see. Maybe a scroll bar or something to provide a visual indication that there is more data off to the side.
- Is there somewhere where you can change your personal gadget defaults - set columns, horizontal ordering and sorting?? Something like this would be cool, it would mean I didn't have to pick all the columns every time I created a gadget (and would overcome most of my previous points).
