Thanks for your suggestion! We actually already have a thread proposing to add a Hitbox function to the Wurst Client. I'll merge your post with the existing thread to keep everything together.
Please remember to upvote the thread if you want to see the Hitbox feature get prioritized, as right now this suggestion only has one vote. The more votes it gets, the higher priority it will have.
And by the way, your English is totally fine. Your message is clear and I appreciate your effort in translating it.
If you have any more ideas or suggestions, feel free to share them.
