As a developer, you have to keep multiple lists in mind:

• The bugreports from users and colleagues
• The latest changes you did on some projects
• The latest changes you are reviewing on Gerrit
• The latest commits that were merged in projects you are working on
• ...

I think the Welcome screen makes a perfect place to show these tasks by fetching the data from the version control systems and bug trackers. The tasks could be opened in the web browser, and diffs on changes could be displayed in Creators Diff Editor.

So, every morning you start Qt Creator, you see at one glance what the day might bring

A start could be made with the tools The Qt Company is working with (Jira, Gerrit, Git) but could be extended to other tools later also.
