Pane width changes with button width (Roll all!/Roll!)
When i click one of the dices the button label switches from "Roll all!" to "Roll!". When this happens it also changes the width of the left pane with the dices ... which also changes the width of the right pane with all the text. Making it annoying to play the game because it happens each time you select the first dice and after clicking Roll!.
Version 3.32.1 in Fedora 31.
Don't know if there is a reason to have "Roll all!" if "Roll!" will work in any situation. So maybe just call the button "Roll!" always.
