I'm pretty happy to have finally found a great application that let me customize my templates and translate it into french. The only problem is that when a client is loggin in, for example, to pay an invoice, the interface is in english and I don't see any option to customize this. I don't care to have my admin panel only in english, but it's important that the instructions and the buttons my clients see are in his language. I propose to add variables that we could customize inside the template sections.
