Timeline & Appointments on debian 12

Hello!

I am slowly but surely translating GNUmed to spanish. (To Karsten: I am 
compiling a list of confusing things to translate, as per your 
instructions in another thread, so that I can ask all things at once, so 
to say, instead of one term per mail!)

All over the things I'm translating there is talk of "Timeline". But it 
seems my version of gnumed, running on debian 12 xfce, and updated to 
the latest version to date (1.8.19) has no timeline item (attached 
screenshot)!

I have found in the timeline project web page a screenshot (apparently 
from 2014, attached) of it on GNUmed. Timeline as such is not available 
in the debian repository it seems. Does this mean that as it is not 
available, GNUmed just doesn't use it? From what I can tell, the 
timeline function was just another way to visualize patient data, like 
EMR Tree?

Also, in the attached old screenshot there is a "Appointments" tab at 
the bottom of the screen to the right of the "EMR Timeline" tab. This is 
also missing from my current version of GNUmed. Could I be missing some 
dependencies, or is this feature simply old and no longer available?
