Bug 496486

SUMMARY
When exporting frames, it seems to default to the last location used. 
This is quite confusing if you are working on several projects. 
In my use case, I make YouTube videos frequently, and use the frame export feature to make a custom thumbnail for each video. 
Each video is its own project, and so it would follow that all the files of each project should stay together. Right now Kdenlive wants to save to the previous project directory, requiring a few extra clicks to make it save in the directory which makes more sense in my use case. 

STEPS TO REPRODUCE
1. Right-click in Project Monitor
2. Click on Extract Frame

OBSERVED RESULT
The previous save location is used as the default

EXPECTED RESULT
The default should be the project directory.
