Okay i figure out that i can Strg+double-click to add handles - but come on… xD
And i can not add handles by simple mouse clicking.
So:
- click deletes handles exept the first one - i also noticed sometimes a cursor jump to the edge
- click and hold modify only the first handle
- can add handles via Strg+double click
What i expected was
- single click adds handle
- click + hold grab handle to modify
- maybe double click for delete handle
- alternate right mouse button options
