I am experiencing regular difficulties with removing hints from lingqs that have several hints. I erase the hint’s content, then press Enter: the hint-field disappears from the widget, but if I get back to this lingq, the hint is still in there.
One thing that I find very annoying is the fact that I cannot delete the text in the hint field of a LingQand leave it blank. Also, I find it annoying that I can’t create blank LingQs on the iOS app. I often want to make a blank LingQ for words when I can’t find their meaning easily, and the current setup forces me to make the hint with one blank space in it.
