* Loader: keep the Apps list alive so closing an app comes straight back to it Closing an application launched from Apps flashed the loading spinner for as long as the list took to come back. An application takes its own view port down inside its own thread, the GUI then draws the next enabled view port below it, and for anything launched from Apps that was this service's view holder, which held a Loading view for the thread's whole life. Only afterwards did the loader join the application's thread and free the FAP, after which the thread called dialog_file_browser_show() again, which allocated a FileBrowser and re-read the directory - a manifest and icon parse per .fap - before any of the list was drawn. The Apps menu now owns its FileBrowser and ViewHolder instead of calling the dialogs service, and keeps the list view set for as long as Apps is open. The list is what the GUI draws the moment an application's view port goes away, and nothing is rebuilt or re-read on the way back. The Loading view is gone with it. Selections and Back arrive as paths on a queue, because a ViewHolder callback runs on the GUI thread and cannot wait for a launch. Each one carries its own copy of the path, taken on the thread that writes it, so a second press cannot rewrite the string while the first is being started. file_browser's scroll timer now only asks for a redraw if the frame it last asked for reached the screen. Its view stays entered while an application runs on top of it, and a redraw request repaints the whole screen whatever is drawn there. Measured on an f7 with a 60 .fap folder: the list comes back in 23 ms with no spinner frame committed, against about a second of rebuilding before; the retained browser holds 13,488 bytes while an application runs; LoaderApplications peaks at 320 of its 764 stack bytes.
