@karimnaguib - In addition to the layout options that the_ducks has told you about, these tweaks may help - there's one to order the custom columns - metadata_edit_custom_column_order - I'm not sure if its applied to bulk, and there's another one for custom column layout metadata_single_use_2_cols_for_custom_fields

Since chaley did some cosmetic but invaluable changes to the spreadsheet, and made it easy set dates and integers to undefined and I discovered I can edit custom comments from there too, I've said goodbye to the Edit Metadata dialogues for single book edits.

I never found a combination of layouts and tweaks that resulted in an Edit Metadata dialogue with which I could work productively. Now I don't care.

ETA : Another advantage of editing the cells is that you can arrange them in a sequence that suits your purpose, intermingling standard and custom columns and omitting irrelevant columns - eg for my journal library I don't have ratings, series or tags on the spreadsheet.
