No autoupdate in data tab

When I change some value in a row in the "Data" tab and click out of the row, HeidiSQL automatically sends an UPDATE to the database. Is it possible to either

1. explicitly commit the changes or
2. at least show a confirmation dialog before updating the row?

I am seriously afraid of accidentally corrupting production data in our database.

Yes, updated data is sent to the server when you leave the cell, but also when you press the "Post" button on the main toolbar, with the green checkmark on it.

So is there a possibility to switch off the autoupdate on leaving the cell?

No, that is not possible.

Then I would like to request a new feature :-)

No need to post a new one - see issue #384.
