OK I've got something which seems to work well using QUuid.<br>
It's easier with QUuid than an incremental id since there's no need to<br>
store the last key.<br>
<br>
It already works more or less, I'll make a pull request soon.<br>
<br>
What do you think about the other attribute ? (which would be called<br>
smthg like "Internal name", and would replace current id's behavior)<br>
I'm not sure this is useful though. Maybe it will only be confusing to<br>
the user...<br>
<br>
Should I add this attribute or not ?<br>
