Feature request to add tabs for multiple views of the same project. Each tab would track which tasks are expanded or collapsed, so you easily click on the tab to switch between the view you are interested in. Tabs should have and editable description too.
With large projects I generally want to collapse most of the tasks, and expand task groups I'm working on. Sometimes I work on different groups and it's a pain to collapse/expand the groups, scroll up/down, etc.
Also I like to print multiple views for various reports. e.g. An overview, stage one, stage two, ...
Having tabs with multiple views would allow more efficient editing and printing.
