I read in another post that there was a way to do this, however could not find anything in the settings.
Any help would be wonderful, thank you! 
Automatic removal of blue words can be turned off in the Settings for the Reader. Just click the gear icon in the top right corner of the Reader. The “Move words to known” option is the one to turn off. However, this just means that when you click the complete Lesson option on the last page, all your blue words for the whole lesson will be moved to known. There is no reason to keep blue words. The idea is that you either need to learn them or they are known. (or you can ignore words).
Hi Zoran, I am sure there are lots of Lingq users, me included, that have that option turned off. Would be long to explain, but shortly, some users are strict with their word count and correct translation of lingqs. But there are days when I just prefer to read calmly without adding any lingqs, checking if their translations are correct etc. I just finish the lesson and leave blue words. Another case, there are days when I find a word that I cannot decide which translation to apply, I just leave it blue and hope after a good night rest will have better inspiration I don’t want that word to become known automatically!
With move words to known I would be forced to either add lingqs beforehand or my statistics would be spoiled by new known (maybe unknown to me) words. Same applies to auto lingq creation - I prefer to check every single added lingq, because some translations are incorrect, for instance in Slavic languages declinations and conjugations require a huge amount of corrections, for example often a translation is not in nominative when it should be.
I am writing this only to let you know that there are some old users (can’t believe, more than 10 years, wished was more regular) that do not really like all that automatization. At the same time I am aware that with such a long time I might have acquired strange and outdated habits and can’t really follow new features. But still, I hope Lingq 5.0 will keep a possibility to turn off that options.
