Make-command : The General Options dialog lets you configure KDevelop's general settings. First, you should set the make-command available on your system. If the selected program does not exist, KDevelop will warn you the next time you're invoking a make command.
Autosave :
If Autosave is checked, KDevelop will save all changed files periodically. The autosaving time range can be set to 3, 5, 15 or 30 minutes.
Autoswitch :
If Autoswitch is enabled, the KDevelop windows will switch on and off according to the usage context, e.g. if you switch to a documentation in the Help-menu, the Documentation browser will be opened, together with the documentation tree and the output window turned off.
Startup :
For starting KDevelop, you have the option to enable/disable the start-logo to be shown during the time KDevelop loads. Further, if you don't like the last project to be opened on startup, you can disable the default behavior.
