I have updated the HTML5 web client on the Connect page. Most notable feature of this new version is that it allows you to click on HTTP links that the BBS generates.
If you want to download a file now, you no longer need to use YModem (and its’ horrid speeds). You can just choose the HTTP (Generate Link) option and click the generated HTTP URL. You don’t even need to copy/paste!
On a side note, YModem downloads in this new version seem bugged and get CRC errors. Just use HTTP.
