One of my two current mods "MT Station Logistics" uses modifications to both the sidebar menu and the detailmonitor framework to provide a menu accessible user-interface for creating and managing specialist station traders. With the new framework it does not seem possible to modify both the sidebar menu (operates in 'fullscreen' domain) and the detailmonitor (operates in the 'detailmonitor' domain. The only plausible workaround seems to be to create two mods which seems counter-intuitive and adds significant overhead to mod version conntrol. Would be grateful for a fix - wysiwyg.
Related issue: atm addons can only specify dependencies to other addons in the same environment. This should be improved alongside.
