Hello, if I pass my KW88 watch to the new firmware,

Hello, if I pass my KW88 watch to the new firmware, is what I lose the advantage of using the launcher of Eric or not.
That little illuminate the top and I saw that the method to install the faces had changed with the appearance of a + key, how do you do with it.
THANK YOU to everyone for your answers.

New KW88 firmware supports installation of watchface from remote server with the + sign, but the new engine is somewhat old and buggy so currently the Clockskin Universal launcher by @Eric_Crochemore is still a better choice.

Buggy because not fully aligned with the clockskin engine that we usually use, so the result could be different and looks buggy…

And it should be fully aligned with the clockskin engine that you usually use ?
