I've always thought that ClimbPro would be so much more useful if it could also be utilized without a pre-loaded course. For example, it could show the profile assuming you keep going on the current road until the next intersection or assuming you continue on the current road for x [user defined number] miles. Devices with maps like the F6 should be able to do this.
Looks like the Hammerhead Karoo can now do a version of this (see 'Upcoming elevation while rerouting'):
