Today I accidentally pressed the backspace key while trying to search for a contact (I know, my mistake). I had a cell selected in a sheet when I opened the contact search. The backspace key applied to the cell, deleting information that I need. Fortunately I noticed and recovered the information, but it was out of sight at the time because the contacts object was covering that cell. I know that getting the backspace key working is much more difficult and a lower priority than releasing a Claude "natural language" search feature, but in the meantime maybe we could at least lock the sheet while an object is open? It's not as if the object is a separate window where we might actually be able to look at the sheet and the window at the same time.
