openpanel save last folder? + symbol input working? + wrong folder message?

When using openpanel (and I imagine, also savepanel), everytime it is banged it opens up in the default folder - in my case, the purr-data installation folder. Should it save into memory the last folder used? This isn't standard pd behaviour, but it is standard behaviour for any other software nowadays.

Also, when in the openpanel-help patch, clicking on the "symbol C:/" message doesn't work, it opens in the same folder as when banging. This works in pd-ext and van.

When clicking on a non-existing folder, it opens the default folder (coherent with ext+van). Would a new message "wrong path" or similar make sense? (and either not open the system dialogue, or keep the current behaviour)
