Tool options in the Start/Add dialogs now remember changes when rerunning tools. For example, in the BLAST tool, the default value for "Filter low complexity sequences" is Yes. If you change this to No, the tool will remember that change for the next time you run BLAST. These changes are saved in your browser's LocalStorage (similar to cookies).

At the bottom of tool Start/Add dialogs, is a new "Reset Options" button. This button resets the options to the default values. If the options are already set to the defaults the button will be disabled.
