When using Searchable labels extra field, the field size is relatively small, allowing only a few words to be visible, and making the list difficult to edit.

Is there any way to increase the size of the Searchable labels extra field field-size in the backend without hacking the core code?

see the attached image.

thanks.

P.S. how about making the field a textarea instead of a text field?

Thanks Fotis, much appreciated.

Meanwhile, a decent temporary workaround is to specify the width for specific extrafields in k2.backend.css like this

#K2ExtraField_36 {
width: 100%;
}
