Hi, thanks for all the contribution, unfortunately currently I am very engaged in other projects and got little time to review and test all the small changes in detail. If you plan to contribute more often, feel free to contact me on the mail in my github profile. We have a matrix chatroom with the developers of Cospend, iHateMoney, the Android and this app

Feel free to separate the localization, dispatchqueues and test-fixes in separate PRs, I can merge those right away

Thank you for your response, I will keep this in mind.
