Rant The dumbest thing about PS CS4 crashing-

Question

…is that apart from losing any unsaved files forever (and when you're saving PNGs or JPEGs as copies, you can forget to save the master PSD file as you go) is that PS hasn't bothered to save any of your swatchest or recent file lists or any of the housekeeping it waits to do until you quit. Surely it could find the odd CPU down cycle to handle that kind of triviality.
Been a few years been meaning to mention that !-\

And please do a search before starting a new thread, quite possibly someone else has already touched on the issue.
Apart from that there are things you can do yourself:
First naturally saving the layered files frequently.
And, probably much less obvious, you could find work-arounds for presets involving Scripts and Script Events Manager.
It was not such an annoyance to me, but a thread in the old Feature Request Forum piqued my curiosity and at least for Brushes I found somewhat of a solution in that every time I save a Brush Preset the whole of the Presets will be saved and on starting Photoshop the brush-preference’s ("~/Library/Preferences/Adobe Photoshop CS5 Settings/Brushes.psp") change date is checked and if it is older than the abr-file’s I can chose to have that loaded.
