Ability to jump to the first and last point of the line

[TrickyFoxy]

1. It would be useful to navigate long lines (rivers, power lines, roads)
2. It is useful when working with complex multipolygons

The workaround I tried to use: selection using
child selected nth filters:0
child selected nth:-1
But they highlight extra points if other lines are connected to the line. And it's also slow with long lines. A native solution would obviously work faster.
