When you pick a file to upload or open from inside another application, the GTK/Gnome file picker does not allow you to have a thumbnail view of all the files. It is a meme in the Linux community at this point since there was a bug filed in 2004 asking for this feature, some even writing patches to make it work. Gnome devs refuse to change how the file picker works however.
Could you elaborate what you by this?
