static keywords

[janmilavec]

When solving the "translate sentence using presented keywords" type of challenge, there is a simple but very frustrating problem:
If, for example, I press the first keyword (which jumps into the translated sentence), there will be a gap left behind, which immediately gets filleb by all the keywords moving one tile to the left.
This makes it incredibly hard to solve problems fast, because if you want to quickly tap the correct order of keywords, and they move, you click the wrong ones. Please stop them from moving, similair to duolingo.
