Sometimes it's hard to remind which slides you have in the desk. So you need to open it and leave the main board with all the desks.
An interesting feature could be like when you add existing slides from other desks to your current working desk, you can quickly go through the different slides to see the content of the desk.
In the main board, that could be great to go through the slides to check if it's the one you are interested in to work with, without having to open it again in the whole tab...

Thanks
