Finding things in a project is not easy without forward knowledge of what to look for, and even then searching is still bound by the contents of a single source file. This feature would add simple global search (scope to be defined?! ideally would support ALL reachable source files, even if the result is initially only displayed in the search result popover when the file is not editable, but ideally, any of the source files should be at least VIEWABLE)

Proposed UI is the same as eclipse/intellij

Just testing what the user experience would be (popover arrow should be right aligned?!)

Alternatively could be done via a editor-centered popup.
