More than one tab [was #11402]
If the Metadata Editor is opened, then its contents changes if you click somewhere else, eg to another file in the XML Editor. That is ok, but you are asked to save the data. That can become unpractical, if you want to use two file more or less simultaneous, eg to copy an information from the inside of one file into the metadata of another file. Wouldn't it be possible to work with two metadata editors (or editor tabs) simultaneously.
