Hi Akiazusa,
Here I am,
I've done what suggested and it, more or less, works. Generally speaking the "dedicated" ARK.lua to be put into .miz woks but with the following.
1) Despite using Russian names in the ARK.lua file (in the plate I would like to see Russian names), the names are translate in English. I understand that this is due to the me setting the cockpit in English in the "special" setup, but it would be good to have this "exception" to the setup and keep original Russian names. I'm also thinking to change the cockpit setup to default, but I need a bit more time to learn and know the cockpit to be able to use it even with Russian text.
2) The callsign labels are out of scale due to character font failure and, either they are not shown, or are too big and with a different font from the channel name (AFD name/location).
Regarding point (1) I was thinking to comment (clear) line 4 of the ARK_MAIN_page.lua, but I would like to have your advice/suggestion on this point.
(Fixed reverting avionics to "Native"... I forgot to check this feature.)
Regarding point (2) I don't know really what to do: I have difficulties to identify the proper lines into the ARK_MAIN_page.lua; more, in the file ARK_usefull_definitions.lua there are info on fonts and dimensions. But I don't want to touch to those if not sure (or more sure, or less blind...) of what I'm doing.
In ant case, thank you again for your support. For the moment I don't mark as solution, just in case we can fix these points.
