Most of the times you will need to apply the same modifies to every demo file, so a customizable Modify Profile management was added to the Modify window.
By typing the name you want to assign to your profile and pressing the Save button
you can create / update your own Modify Profile.
Every Modify setting in the window (except the Modify this match checkbox obviously) will be saved in the profile so you can later select the profile from the drop down list and quickly restore your settings.
To remove a previously created profile just select it and click on the Delete button
