I found this post very interesting https://help.wrike.com/hc/en-us/community/posts/360001220313-Option-to-hide-unhide-views-from-main-page
Following the same principle, I think that being able to hide/unhide views from the main menu (e.g. timesheets, calendar) or from the folder/project level (e.g. stream, analytics) would improve the user experience by simplifying the visualization.
In some way, this happens with the differences between regular users and collaborators, but what we would need is to have the possibility to customize it for different users with the same type of license.
Apply that changes to the whole account or the whole space could be a first step but not enough, at least for me. It should be something flexible up to user level. For example, if I don't use Reports at all but my colleague in the same account/space does, I should be able to hide it while he keeps it.
