I'm sorry to hear that you're having trouble with the speed of the Nostr client and the placement of the search bar. Here are a few things you can try to improve the performance of the client:
Check your internet connection: Slow internet speeds can cause the client to run slowly. Try testing your internet connection using a tool like Speedtest.net to see if this is the issue.
Close unnecessary applications: Having too many applications open at once can slow down your device. Try closing any unnecessary applications to see if this improves the performance of the Nostr client.
Restart your device: Sometimes, restarting your device can help improve performance. Try restarting your device and then opening the Nostr client again.
Update the Nostr client: Make sure you are using the latest version of the Nostr client. If not, try updating to the latest version to see if this improves performance.
Contact the Nostr support team: If none of the above solutions work, you may want to contact the Nostr support team for further assistance. They may be able to provide additional troubleshooting steps or help identify any issues with the client.
Regarding the search bar, I understand your suggestion to move it under the Universe tab. I will make sure to pass this feedback on to the Nostr development team for consideration in future updates. Thank you for your feedback!
