I've been using the latest version of Pycharm and they have added an open directory feature to quickly open a directory and start editing the files instead of having go through the new process wizard which is overkill for using Idea to edit python projects. This by the way seems to create a project out of the folder you opened too.
Also Netbeans has a favorites feature that lets you directly access the file system and add directories to manage directly within the favorites panel. It even picks up versioned files and let's you manage them that way as well.
Are these features something that could be Added to Intellij Idea? It's really been the one thing that's been keeping me from switching, no simple way to edit files and folders without creating a project first, and sometimes the "project" you want to open doesn't really fit into the option set inside the project wizard.
