there is a misunderstanding. I do not mean a Who is online module for the complete page. I would like a module to indicate who, say in the last twenty minutes, was online on the chat page. I have no idea if you can use the Joomla module in this way. Some time ago I had a chat that had such a module and showed the users if someone is active in the chat, I wish that again. I run a small retro style community, in the past many chats had such an ad. In the last few years, I have tried pretty much every available classic Joomla chat, all with regular use have serious quirks. Smart Schoutbox makes a very good impression as a chat so far.
Where we are already on the subject of wishes for a new version. Maybe you could also incorporate a color management or different skins with light and dark colors. I suffer from an eye disease that makes it difficult to read on a white background, with dark backgrounds I get along much better.
