Fiddly edit pencil button on field editor component

I find clicking the edit pencil button on a field a little fiddly on the field editor component. Could this be made to be displayed on hover for the whole nx-basicfieldeditor-item rather than just the nx-fieldtext area? Also, could you use css to hide and show the button rather than javascript so that we could use css to override these hover effects and show the pencil icon the whole time (except greyed out), for example (like how Salesforce’s field editor works in lightning).
