Give an option to avoid tracking history of your search. It is really painful when you open the app to look for a translation with someone else and you are forced to show them what you were translating last month. And is great that there is an option to clear the history but I happen to forget to clear it sometimes, then open the app in front on the wrong person and is NOT fun.

Do you mean for the roman transliteration of Thai words?

The dictionary somewhen stopped working in offline mode except for words already stored in the cache. It still uses 1,8 gb of space though. The lookup function in the pop-up menu ("Longdo Dict") unfortunately also ceased to work quite some time ago. It requires an inconvenient copy & paste now. Overall a great dictionary, it deserves 5 stars if these features come back to life again.
