Auto lookup clipboard not working in floating window

I’m using iPad Pro 10.5 with iOS 11.4. When using Mdict as floating window (some app wont allow split window), if I copy a word from background app, Mdict wouldn’t auto fresh and show up the word. I have to quit the multitasking and open Mdict solely, and only in this way the auto look up become actually “auto”. Pleeeeease fix this. Thank you!

Awful New Update

In the new update (version 2.0.11), if I change the size of fonts, the sentences in the result page, go out of the frame. This new update put me in trouble so much, and I had to restore my backup on my iPhone to recover the previous version of the Mdict app (2.0.10), and it charged me about 30 GB of traffic data and wasted lots of my time. I hate this update. I never ever rely on new updates of this app.

This software is so practical and useful dictionary and fulfills you buying expensive dictionaries, something you need is just searching on the Internet for banks you need and add them into your software. The banks should have .mdd and .mdx extension. These are some suggestions from me:

1- For instance I type a word for looking up and the dictionary shows me some options, as I choose one of the options, the option word is replaced with the word which I had typed and it bothers me (I think if the typed word stays fixed, it's more convenient).

2- Whenever I update the dictionary, I have to rearrange the library again.

3- If the dictionary supported fuzzy search it would be more practical.

4- If the dictionary had leitner box which notifies the word review which we add from dictionary as a notification and also having the word of the day, it would be so fantastic dictionary.
