I've noticed this problem since, I think, L 6.12. When I create a reading plan then go and open the resource, the reading plan visual filter does not automatically switch on. The first time I use it, I have to click the three-dot triangle button and manually switch it on. I can't find away to make it come back on by default for all resources for which I've made a plan. Right-clicking/ctrl-clicking etc. doesn't seem to do anything. Help?
