It would be nice to have a complete restyling of the User Interface to have a more enjoyable "look and feel" and a modern User Experience.
In addition to the colors and icons, e.g., also to have a way where the U.I. is "self-configuring" by the user: the user, based on rights, may add buttons or icons (such as Micorsoft environment in Business Central) also for external functionalities (e.g. Mail, ERP, Company applications). This to have Docuware as main interface to your work.
