I noticed a small change to the git icon if I am correct.
I don't know how high the frequencies of any new visitors (or potential new member) would check the home page.
I think the home page may need a complete revamp in design. Maybe try to use AI to help making it look more modern.
Add some kind of announcement or news bulletin section at sidebar such as new versions or beta releases, libraries update. etc.
A short summaries of hot topics discussion (last 3 posts) happening in the forum. It may give impression the site is very active.
Is this adding clutter?
Or set up a poll for members to suggest improvement.
