New tab should take name of file as default title
When adding a new tab of a file type, e.g. Word, the tab gets the default title of the file type, in this case Word. One now has the option to rename this. Often a person forgets and only afterwards realize you should rename the tab. This is easily done, but the message in the conversation space still shows the old name which is not ideal. The tab should rather take the file name as the default title. This can be overwritten when necessary.
Alternatively, when the file tab is renamed, so should the message in the conversation space be changed.
