Hello.

1. Crash with timeline/queue window:
When closing (with the 'X' on the window) a windowed timeline/render queue ('Timeline/Queue Window' checked in the 'View' tab),
that does not uncheck the 'Timeline/Queue Window' in the 'View' tab, and the timeline/render queue just disappear (you can not drag it back with the 'dots' in the bottom either for the timeline),
repressing the 'Timeline/Queue Window' in the 'View' tab will make it reappear in their normal location,
and finally, when repressing it again (to make them in window mode again), the program crashes.
2. Flipping a path:
So, flipping a path (both vertically 'V' and horizontally 'H') will flip that paths node rotation axis (the rotation gets inverted)

Thanks for your time.
Wish you all the best!
