Hello. I really like the idea that when I'm opening for example Core Settings, Explorer Panel settings and File Search they are opening inside the panel, just as new tab. It's natural behavior because users of double-panel file managers are used to operating on panels with tabs. Can You consider making all popup windows to be opened as tabs inside active panel? All actions that require some additional space (like Ctrl+F popup window in File Search) could be integrated to the panel as well. They could be minimize into a small bar (with for example name and shortcut to maximize) on the bottom/top of the panel and when pressed this will slide up/down just to set some additional settings. In case of File Search one could set search query, press Start and the popup window fill be automatically minimized to the small bar. How about that?
