maybe the launcher can be location agnostic and remember somewhere the
locations of the lasts images that where opened with it and simply offer
links to open the ones at the lasts, say 7 images, paths. You will even
evade coupling that to the OS
where do you store the images that the launcher creates?
I�m not currently using launcher but if I�d use it, I want my images pretty much as I already described.
Because I move stuff from OS X in development to linux in production I�d hate things coupled to hidden magic places because it will force me to either search for them every time or complicate git repos (injected resistance) or not use the launcher at all (removing that resistance and the alleged convenience it would fail to provide).
Therefore, my suggestion is to keep it location agnostic
