Dennis,
Thank you for the feedback. All your findings are correct. It is very encouraging seeing new feature being
fully utilised in such a short time.
Regarding naming conventions - yes I try to keep the "Z-order" name for new z-order feature
and do not use the word "layer" to avoid mix with old functionality. So, I would like to avoid names like z-layer.
In fact the drawing studies (lines/rectangles/elipsses) can use both functionalities *independently*.
The z-order defines the drawing order (above/below), while the layer controls visibility (on/off) depending on interval displayed.
Having two as independent controls was intended and provided for maximum flexibility.
If anyone has better ideas on naming conventions, they can be changed.
For me "z-order" name represents actual functionality best. I have some doubts regarding "layer" word, because
this old functionality actually is just visibility switch.
Best regards,
Tomasz Janeczko
