Currently, each time we open a file, it overwrites the "last path" destination and this one is reused by the "Ctrl+E" export feature.
That would be nice to store two different paths, the one when we want to open a file and another one to remember each time we want to export a graph because while working we can export several times and most of the time it will always be in the same export folder on our computer.
It is a bit time consuming to browse once again to the right folder.
