Who the heck decided that the 'Delete' option under the Tab menu, that's grouped with the Add Tab and Rename options and that normally just deletes a tab, deletes YOUR F'ING ENTIRE PROJECT when you delete the first tab?! Why would it delete the ENTIRE FOLDER along with everything else instead of just the one tab?!
Make it DAMN CLEAR in the confirmation that deleting changes will delete EVERYTHING instead of just ONE FILE like it normally does. Or better yet, grey the damn 'Delete' option out on the first tab instead of providing a way for the user to destroy all their work with one click. Why would someone ever want to delete EVERTHING through that menu? At least using the OS's file manager they can undo it!!
