Kudos for the entire team!
I am particularly enjoying Jamovi and I believe this is a great step forward for students and poor/lazy-coders like myself.
I am using the mixed models of the GAMLj package and I really like it.
The only one thing may work best for the analyses I am currently running would be having the opportunity to apply user-defined coding for factors (for example I cannot simply contrast level 3 vs. 2 while contrasting 1 vs. 2 as far as I can understand). Not sure if this is something the developer may find useful.
Thanks for this great piece of software!

Factors coding in GAMLj mixed models
Re: Factors coding in GAMLj mixed models
Hi, @eval.
You have already taken a look here:
https://gamlj.github.io/rosetta_contrasts.html
In addition to choosing (Factors Coding) the type of contrast, have you tried to sort the levels of the Variable (DATA-> DATA VARIABLE) differently, compared to how they are by default?
Example: from (1 2 3) to (3 2 1) or (3 1 2) etc.
Cheers,
Maurizio

Re: Factors coding in GAMLj mixed models
Dear Maurizio,
thanks for replying.
I think I did. Let's assume 1 is my control level.
Almost all the coding options won't run a plain 3 vs.2 without ditching the 2 vs. 1 comparison.
The Helmert will run 1 vs (3, 2) and repeated will compute 2 vs. 3 but not 1 vs. 2.
So eventually the full set of comparisons can only be obtained with the posthocs.
But I may miss something!
