I agree, there should be a limit., but this is confusing for the user.

In Dimp, there is no way to work with only some folders (say, personal  
folder and no shared / other user namespace) and access the other  
folders in a more static way like in Imp.

In this case, there are shared folders with customer informations (a  
customer = a folder). They are nested (no more than 100 at a given  
level, so if it where possible to request and display only the top  
folders it would be ok.

I'm not that experienced in web programming (especially json, ajax  
etc), but isn't there a way to ask IMP the top folders list only, and  
to refresh the list only when a subfolder is requested ?

I know there is a hook to hide shared folders, but when using it, is  
there a way to access hidden folders (other than going to imp) ? Also,  
would this be a setting that could be changed for some users only ?
