A restructured sidebar with a dedicated Changelog

We've cleaned up and restructured the sidebar to make navigation more intuitive. The main application features you use for daily work are now grouped at the top, while help-focused items like support and feedback have been moved to the bottom where they're still accessible but less in the way.

We've also added a new "Changelog" link to the sidebar. This is where we'll keep you updated on all our latest releases, improvements, and new features - basically what you're reading right now. We believe in being transparent about our development process, so you'll always know what's new.

The reorganization should make it easier to focus on your core workflow while keeping administrative functions readily available when you need them. It's a small change, but one that should make your daily experience a bit smoother.
