Field Calculator - Apply button

[ERHash]

Feature description

Hello,

I suggest to add a "Apply" button on the field calculator for update many fields in one time

Thanks

Additional context

version 3.20

What version/OS are you using? 3.40 on Windows has an apply button, as do most QGIS 3.x if I remember correctly.

Looking at window icon, this QGIS 2.x

Please update to a supported version that has this already.
