Quick fix for the "'action with id "Options" isn't registered; action will be added to the "Other" group'"
exception when starting IDEA. The 'BackSpace Stop at Indent' was moved to the Tools-Menu.
When HungryBackSpace plugin is loaded, the BackSpace key is modified to hungrily delete whitespace.
When hitting the BackSpace key will consume all preceding whitespace, including newlines and tabs, until a non-whitespace character is encountered. If no whitespace preceded the caret, then HungryBackSpace acts like a normal backspace and deletes one character.
This feature helps free your mind to concentrate on coding instead of counting out the number of BackSpaces? required to go back to previous line. Try it and you may quickly become addicted!! IMO this should be the default behavior of Backspace. IDEA should add an option Editor->SmartKeys->Hungry Backspace.
For those familiar with EMACS, HungryBackSpace works the same as CCMode's auto-hungry-delete.
