I need to do that ("save" in the HTML pane) with many of my items because in the past many items were saved in the DB with their link to their respective MHT files, but without any content in the itemHTMLtext field... Which makes it impossible to search for certain items content.

 

This wasn't a problem until the latest release.

 

1- focus on an item linked to an MHT file

2-  press "save" to fill the itemHTMLtext field with some data

 

You should get a message asking if you want to replace the current content with the content of the previously focussed item.

Which isn't right, of  course.

 

I can attach a screencast if the explanation isn't clear.
