Hi, I love Pleco and I think it is very optimized and user friendly, but I found something I think could work better (at least for me). Sometimes I search a word, and after that I search another one which has some kind of relation with the previous one(s). In that case, for comparison I want to go back to the previous one(s) but I have only two options: a) Writing the word again b) Going to the tool bar, choosing history and then the word I want to look up again. Sometimes I have to go forth and back again two or three times, which makes the process very slow. Maybe some kind of gesture or arrows could make it much faster.
