How can I set my start page to viewall my projects.
You can set a start page to any view by going to Settings (gear icon in top-right corner) -> General and choosing "Custom query" from the drop-down menu.
Unfortunately, there is an issue with this option right now (which makes it impossible to use this feature) and we're working on fixing this problem. Sorry for the inconvenience.
This issue has now been fixed, you can use custom queries as the default view and define the query in Settings -> General.
