One thread with 100 posts is no harder to search than one forum with 100 threads.
The only practical solution requires considerable effort from moderators or a little more effort from users, neither of which is likely to happen. Perhaps, if the moderators were ruthless, users would learn to follow the rules:
Search before posting (or moderators will just delete your duplicate post)
Post only one request per post (or moderators will edit your post to delete all but the first feature request)
Don't wander off-topic (or moderators will move your post elsewhere or delete it)
Limiting the number of posts per day will only hamper feedback, which the developers want to encourage, not discourage. Just keep it concise, and post it in the right place after checking that it's not already been done by someone else.
Du kannst nicht von Vivaldi importieren, du musst die Dateien kopieren und einfügen -- du kannst natürlich auch gleich den ganzen Ordner ersetzen wenn du alles wiederherstellen willst. Wird aber nicht für Erweiterungen funktionieren. https://help.vivaldi.com/article/full-reset-of-vivaldi/
