Double click for zoom out

[lpatiny]

For many features the simple click has no effect so have a double click for zoom out is acceptable.

This is the case for the zoom tool, apodization, phase correction seems to me. In those cases we should allow the double click for zoom out with or without shift.

From my point of view, the behavior should be consistent across all tools. I think we should reduce the number of edge cases rather than introduce new ones.

But if you prefer to go in this direction, it is up to you.

I would like at least to have the double click when the zoom tool is active. I agree that for other tools it is more complex to manage.
