When working with Inventor, I find myself browsing the the project folder for almost every command, Place Part, Save, Open, Export, Create New Part, Add Assembly. These commands only need 1 previous folder setting.
What the real complaint here is, we work in a 'single project' vault environment. Our real project folders are all organized under a single inventor project (otherwise I'd have some 300 inventor projects at any given time). In this mode, we are jumping between projects a few times each day, and if we are not VERY careful, Inventor will let us place our new file in the other project folder (the wrong folder). Many files get check into vault that way, and if it were not for Vault's very nice search engine, these files would get lost.
So now for each command I have to check the folder I'm in, and browse to the folder I want to be in, because it has MANY previous folder settings (one for each unique file browsing capable command) instead of 1, the last folder I was in.
Please make all folder/file search commands reference 1 common previous folder value (especially in the workspace locations).
