[x] I have checked that the changes included in the PR are intended to merge to master or any destination branch.
[x] I have verified that the new changes do not break any existing functionalities, unless the new changes are intended and have approved by the team.
[x] I will take care of the merging and delete the side-branch after the PR is merged.

Let me know if there are other preferences!! i think matching card, questions page and the history table ui can be left as is :D
