The new motion path feature was just added recently; however, when creating a new motion path, the default frame range is 1-250.

The idea is to replace this useless range to a context dependant one.

Many frame ranges possible for this purpose :

preview range
scene frame range
last-used motion path range
object keyframes range (from first keyframe to last)

Options :

1- Make by default the range to be the scene preview range.

2- Or, the "Path type" property could be changed to "Frame range", and contain these situations :

- preview range
- scene frame range
- object keyframes range (from first keyframe to last)
- custom range
- around frame

I think what you propose is generally correct, I'd also like to see a proposal for these options to be implemented in the right click menu for creating motion paths.

which is where I feel we should put more energy because now it's the actually more handy one that i believe animators use way more.

I think a dropdown could fit there with all options listed :

preview range
scene frame range
keyframes range (from first keyframe to last)
custom range
around frame

What I think would be perfect is to have the start and end property exposed, but slightly darker, and when modifying a defined range( ex preview range ), it switches to custom range (normal light then).

This design task was discussed in the last Animation & Rigging module meeting. Overall people are positive about the design. Especially thearound frameand*selected keyframe range// options are already highly anticipated :)

I think @LucianoMunoz 's idea is also good. By having the "Add Motion Path" functionality as an operator that can be triggered at any time, it can pick up on the then-appropriate values. For example, if there are any keyframes selected it can use that range, and if not it could either go for "around frame" or the preview/scene frame range. Such context-dependent values are harder to do from the current properties panel (finding the first/last selected keyframes is kind of a slow process, so I wouldn't do that on every redraw of the panel).

I'm so sorry for my inactivity. I'll do it in the following days.
