Add Recent Tab for video player Image viewer Document viewer
In Document viewer add "Recent" as first tab and Filesystem as second tab (and perhaps Gallery tab like in image viewer and video player as third if it possible)and remove forced select Document in startup exactly like in video player and image viewer just allow user choose the required tab
In Image Viewer and video player just add "Recent" as first tab and keep filesystem and gallery as second and third tabs
Explain : "Recent" tab keeps all opened Docs or images or videos histories as All sessions records by thumbnail exactly like in Speeddial by days by weeks by months by years all these must be separated from eachother by an separator
this feature is benefit for quick access to most usable docs or videos or images recently have been opened to save user time....
