Is there any way to specify fixed viewport pixel dimensions (width, height) for displaying results

I would like to have recoll always open with a fixed size of the viewport for the results display.

I would like the other elements of the recoll window to be pushed "out" (up, down, left) for those to still display correctly, but to always have the viewport "claim" a specified size. For example, the following image shows the dimension which I would like to specify:

Recoll__WindowDisplayWidth

My suggestion would be to allow user-specified values for ENVIRONMENT variables, such as

RECOLL_RESULTS_VIEWPORT_WIDTH="900px"
RECOLL_RESULTS_VIEWPORT_HEIGHT="400px"

I did a quick scan in the code and I located references that could be related (but I don't understand any of the coding):

columnViewportPosition
globals.OutputWidth
restableColWidths.size
res.columns
