Perhaps this really should be in the standardized dialogs for whatever window manager, but NS is bad about it's file save dialog. Could we get a way to save preferences, based on a regex of the URL, for the initial directory that the File Save dialog puts you into? Also great would be creating directories, removing directories, and automatically sequencing for duplicate filenames. Say, if you go to www.dailylandscape.com, it would automatically select /pics/landscapes , where www.clipart.com/anims/ might go to /webart
Some of these requests are implemented post M10 (not sure where you're coming from). Some of those don't work on Unix yet. The features in the standard file picker dialog are outside of our control. We remember the last-saved-to directory (and store it in prefs so you see it next browsing session). I don't remembering different locations per url is feasible at this time. To use the info is relatively easy. But adding a prefs UI to edit the regex list is a bit beyond our resources. I'm going to move this way off to the future but when we get there, it still probably won't be a high-enough priority. But thanks for your input nonetheless and if you'd like to take a stab at doing the implementation yourself, I'll be glad to help you out.

Move to "Future" milestone.

A simpler approach (than regexp-based) that wouldn't require any UI would be just to make it per-hostname, i.e. www.some.where and www.else.where would each "remember" their Save directory, with a default for new sites (or this could start from the most recently used one, as at present). I guess you might want UI to clear the (otherwise ever-growing) list of hostnames, but to start with (at least) this could be done behind existing UI for clearing the history.
