Hello!
Let me start off by saying that I enjoy the reading tool - it's not overcomplicated and has all the necessary functions I can think of (at least so far as I have been using it for about a week or so).
Apart from a dictionary related issue I have (already posted about it here https://languagecrush.com/forum/t/2095), there is something else that bugs me when using the desktop reading tool. I would normally read a text and have the translation loaded on the right side of the screen. Whenever I click on a word I want to mark in red or green, this would replace the translation text with the word's vocabulary entry. After I close this, it pulls up the translation once again, however, it goes back to the very top/beginning of it. Thats quite annoying as I have to scroll down to the desired passage I left off from. Not only that, but even if I highlight a word/piece of text from the translation as a bookmark if you wish - it's gone after the right part of the screen switches from vocabulary to translation text...
I hope I managed to explain this well:) If necessary - please let me know to provide further details/screenshots.
Thank you!
