I think some users here frequently typing usernames manually, or sometimes need to copy and paste to mention usernames in their replies, so I have an idea to make this process easier.
Note: I’m experimenting with using AI for codingThis time, it’s not create a website, bot, or extension, I decided to go with a userscript because I noticed a lot of users are already using a lot of extensions for BitcoinTalk.
Example of the script’s output:

HOW TO INSTALL:
1. Please install the code:
https://greasyfork.org/en/scripts/593647-bitcointalk-mention-autocomplete2. Be sure to scan it on VirusTotal first
3. Install
Tampermonkey (if not installed yet)
4. Make sure this is enabled:
https://www.tampermonkey.net/faq.php?q=Q209#Q209 if the script fails to run.
5. Once installed, open the thread and reply, type @ and the username autocomplete will appear.
SCRIPT INFORMATION:
1. This script only works on bitcointalk.org
2. This script requires your local storage
3. This script will store maximum 10,000 usernames from the threads you visit.
4. The script only crawls the first 3 pages of each thread to prevent blocked IP (limit rate) by bitcointalk because of unusual crawling
5. The script only saves data once for each username
HOW TO DELETE/RESET DATA

1. click the Tampermonkey extension
2. find “Bitcointalk Mention Autocomplete”
3. select “Reset Consent” to revoke permission to use local storage
4. select “Clear Usernames” to delete all stored username data
UPDATING SETTINGSIf you want to change the script settings from crawling 3 pages to lower/higher number, or change the username limit from 10,000 to lower/higher number, you can modify the code line:
const MAX_PAGES = 3;
const MAX_CACHE = 10000;
how to modify:

1. Click the arrow > to the saved bitcointalk mention script from your tampermonkey extension
2. Click “Edit,” and locate the two lines of code above
3. When finished, select “File” from the menu and click “Save”
