At our company, we write a lot of comments into the comments section of the bugs. It would be nice, if all developers involved in the project would get to see if there are any unread comments in the bug reports.

This would be best if there would maybe be a small exclamation mark, somewhere by the bug report name in the project view. Or a notification in the notification area, but that would be a bit to unsubtle probably...

Store user preferences for bug list in local storage or cookies .

Emails are not going through to any inbox. Tried gmail, hotmail and yahoo. I have tried multiple times and have even created new accounts but have not gotten any emails to go through. It worked as recently as 2 days ago.

Being that comments can extend the page and Change status is one of the last actions, have the same at on the top back to project..

The other option is to add a button in Status called <Change and Return>

Its more convinient to be able to click the url user made his submission from, to track the problem online.

There needs to be a date due option when creating a bug.

AFAIK the only way to select project is from the Dashboard.
We work with many projects at the same time which makes finding and selecting the correct project involving a lot of scrolling, looking for the right one as it seems to be sorted based on creation date? I like the dashboard view so what I'm requesting is a complement that is more compact, more like a listview of your projects, or a way to sort projects.

If you would be able to set who is in charge of a project, then the sorting of the projects could start with the projects You are currently in charge of aswell as latest changed.

Lot of ideas in one post. Feel free to split up :)

A timetracker should be implemented into the bugreport function, a teammember can add how long they've been working on a bug. Or if the bug is "In progress" and the status gets changed to "Resolved" the time you've been working on the bug will be filled in automatically 

When reporting a bug, it would be nice to have the ability to check which Testcase it came up on. I also think Testcases should "exist" in a similar way Bugs do: with more editable fields and interactivity
