Suggestion:
Start search-process by clicking a search-button (for the search by language page).
As far as I can tell it remembers my last search-options and starts searching sentences as soon as I call the search by language page. Furthermore if I want to change more than one search-option I have to wait after every change for the search to finish, to be able to change the next option. This seems like a waste to me. Or is it just me having this issue?
No it's not just you. It's the current default behavior, I agree it's annoying. It was already reported before.
We'll fix it someday. I have created an issue for it: https://github.com/Tatoeba/tatoeba2/issues/627
