It would be nice to have a form where we can quickly change tab/visibility (especially the last one) for a larger number of fields and subfields in a particular framework. Often you want to hide a (sub)field and set tab to -1. Or unhide a (sub)field by restoring tab and setting hidden to 0 (or possibly another value). In order to select fields we could use constructions like: 100|110a|200|300abc etc. Or regexp based: /^1|^20|300[ab]|500a/ etc. And all fields selected, perform a hide or unhide operation. Do you have suggestions about its interface?
