A frustration I've encountered several times, the solution for which seems like a pretty intuitive change.
I mark a series with the 'Plan to read' action, then start reading it at some later point. However, because chapters don't get marked as read when a series is under 'Plan to read', despite my opening and reading chapters - they don't marked as such, and I lose track of where I was when I return to the series.
It seems simple to implement - when a chapter is opened, have the action for the series automatically change to 'Reading' (at the very least for series that had been marked 'Plan to read'), and opened chapters become marked as read.
