Hi Stefan,

Continuous feature drawing is already possible, but is disabled by
default, as in the overall, it slows down rendering.

If you want to enable it:

Settings --> Options --> Rendering & SVG --> Rendering behavior -->
"Number of Features to draw before updating the display" --> set it to > 0
(e.g. 10000).
