PLEASE make the default folder for "save as..." the same folder as the file you are working on is stored in.
Today when you use "save as..." you are directed to the folder you used the last time you used "save as...". Doesn't matter if it was a totaly different file on a totaly different day in a totaly different session.
This idiotic behavior just caused me to overwrite the wrong file and continue working on it for half a day. Now I have to fix it in time machine and I will loose almost half a days work.
