Font sizes in forest plots and plot.baggr_compare (add_values)

[wwiecek]

I feel like I am using forestplot package wrong, my forest plots are ugly and the point sizes are way too big sometimes. THere has to be a good automated alternative.

Similarly, my own solution to printing values in

bg <- baggr(schools)
baggr_compare(bg) %>% plot(add_values = TRUE)

requires manual adjustments via values_size and values_digits. This is bad! I'm sure there is a better out-of-box solution for adding these values on the right hand side in a way that doesn't require the user to make manual adjustments.

Can this be considered closed with #179?
