Salut bev,
I can understand that you want to have you mod show up with a lot of search results. I can also see why many French people would like to have this translation mod and that you want to make it easy to find.
But you have to understand that by far most people don't need the French translation, so for them it is pretty annoying to always see the very long title of this mod.
So I want to suggest a compromise. Only keep the very well known mods in the title and move the rest to the description. I think that this way everybody will still find your mod. If someone already knows this mod exists they can look in the description and find the mod they want to have translated.
For instance if someone is looking for "Bob's Greenhouse mod" they already know about "Bob's Logistics mod" so they don't have to find this French translation mod, because they already have it installed ;-)
This way the description might still be longer than other mods, but it wouldn't take up the whole screen. I hope you are willing to do this for all the people who don't need this mod. Keep up the good work by translating as many mods as possible, it's not an easy task!
