It is very difficult to use the web client to work in multiple areas at the same time. It would be nice if it could function more similarly to the windows client and open in a new tab.
If it is opened in a new tab you have the ability to work on multiple things at the same time and compare information.
The way it currently functions reduces the usable space on the screen as they are stacked on top of each other making smaller and smaller space.
It is also difficult to get back to a previous screen.
