This is a software made for serious study for people who want so seriously to study that they have paid a good deal of money to be able to do so. More often than not, my time with the software is cut short from eye-strain. A dark mode as well as an amber mode with this type (text dependent) of software should be a given at this level of developement. I'm questioning my purchase. It's amazing but what good is it if I can't use it because it causes eyestrain and migraines.
Furthermore, it seems that you are ignoring a large base of customers who have very kindly and with good laid-out reasons requested this function, because you won't even respond to these comments. So, please give us an update or have the decency to give us a direct denial.
