Salut simjoubert,
i think your plughin is very very good, I will use it for shure,
my wish would be that you add a funktionality not only to add new attributes with new values or strings, but also change existing strings or values in existing attributes, that would be really nice for me.
A second thing would be nice: Add the possibility to assign a sequential number additionaly to the text, perhaps like String&seyuentialnumber---> perhaps EL_1 ...EL_2...EL_3 and so on

Si vous le souhaitez, je peux vous aider à traduire en allemand...
Cordialement
