I just used this to find and replace one small change in a number of places.
I just lost a whole ton of formatting that I had just completed.
There is a toggle switch to toggle find replace style HTML or plain text.
When the toggle switch reads HTML it will replace using plain text.
I did this and resulted with a bunch of product descriptions with a block of unformulated plain text, all my carriage returns and all formatting had gone.
This was very frustrating.
Was prepared to buy the product and use on the odd occasion but it looks like I'm best to to all updates manually.
