Here's a new version of FileBrowser with the following changes:
Fixed Bug: Deleting a file while in "Autoscroll from Source" mode in FileBrowser sometimes caused an Exception.
Added actions to go back and forward in the browsing history. Default keys assigned are like in the rest of IDEA CTRLALTLEFT and CTRLALTRIGHT
The shortcuts for the actions "Go To Parrent" (default: LEFT) and "Activate selected file or folder" (default: RIGHT or ENTER) can now be changed via IDEA's keymap settings
Displaying the parent in the file list can now be switched off in FileBrowser's application settings (File -> Settings -> IDE Settings -> FileBrowser)
It's not possible to navigate to the list of roots from within the file list anymore. Currently only by using the "Go To" action the root can be changed. A roots-menu will be added soon.
P.S.: I'm on vacation for the next two weeks (without Internet access). So any questions or bug reports that come up during this time, will be answered when I'm back home.
