Currently it seems it is only possible to select one of the predefined zoom levels.
I suggest the implementation of more way to zoom:
\- specify an arbitrary zoom level in a text box \(e\.g\. 65%\)
\- "zoom to selection"\, to include in the zoom only the content of a selection\.
\- "zoom to mouse\-pick"\, where I select with the mouse the zoom rectangle area\.
I work mostly with a touch pad, instead of a proper mouse, and not having these features makes it very hard to browse the drawing with the gestures available.
Thanks for your consieration
