Redmine

A great User Experience feature would be to quickly set flags or stars in the issue page and being able to sort the list accordingly.
I think of something that could be triggered with a simple click, like in gmail ( Start > Blue Star, Green Check, Red Check ).
Ideally these flags would be private for each user and would not affect the status of the issue itself, different users can set different flags on the same item.

For example, you could quickly put a star on the issues you want to work on today, then sort them to the top of the list.
No need to open them and change the priority or any other field.

Thanks
