I don't really remember enough about Excel anymore, but considering that I don't remember having that problem despite how many years I used it, I guess that is the case with it.

And yes, a toggle would be nice. In fact, a few months ago, I was thinking of putting up a request over to the LibreOffice team, when I was working on the table view of another OSS project, but then procrastinated until I forgot. Honestly, if there are enough people that have a problem with this little thingy, it'd be better off fixed. Specially in the Qt implementation at least, it really is just a boolean toggle even for the developer.

Would you like to put up a bug report to them?
