The system seems to freeze up rather consistently when creating Linqs with the the Enter button. I have to reload the page or move onto another lesson and return. At least one time per lesson I would guess.
The K button isn't reliable either.
Often when I "search dictionary" because the enter button won't let me create a lingq, the hints that are already there get erased and I'm forced to check the dictionary and retype my own hint.
When trying to clean up the library by moving lessons to "archive" ... some won't move. I would like to have a library with lessons I want to learn, not full of stuff that is of no interest to me. Not all lessons are created equally. On this note, I think it would be wonderful if there was a "general library" from which you draw resources into "my library" from which you draw lessons that are stored in "my lessons" that can then be archived as "completed" or "semi-completed" etc...and properly rated for future users. Sometimes it is only after you study a lesson that you realize how useful a lesson really is. Snap decisions can cause roses to get given too soon, or roses not to be given when they really should be given.
And while I am at it, for Korean especially, is there not a way to be able to have a third color to be able to identify grammar patterns? So that the grammar patterns show up, regardless if different words are being used. Quite often these patterns are so similar to one another that it takes extra effort to learn them all. All the 는s 지s 을s 다고s etc...
