Re-exporting GIF

[chrs1885]

Once the user has finished recording a window/screen with a preselected frame rate, she can trim and export the GIF. After exporting was done, there is no way to adjust the result (e.g. change frame rate).

As a user I'd love to have the opportunity to navigate back to the trim window in order to re-export the video with new settings.

Simply provide a back button as part of the "Export finished" screen.
