There is a really great feature in Twhirl that displays a small yellow star at the top right of all new and 'unseen' tweets - which I'll call the tweet's 'unseen status'.

I think it would be really great if the Twitter servers would monitor each tweet's 'unseen status', rather than it being done on the local machine, via a Twitter client like Twhirl.

(The guys at Twhirl sensibly pointed out that this 'unseen status' feature needs to be in Twitter before they can add it to Twhirl)

This feature would help tremendously when going from one machine to another (from work to home for instance) - when both machines have Twhirl logged into the same Twitter account.

The Twitter client could update the Twitter software (on the server), on which tweets had been 'seen' locally - and this could be done at the same time that the normal network-API-requests/auto-refreshes happen.

I've included two images to illustrate what I mean by this 'seen' flag...

This 1st image shows when a single tweet is cliked, and therefore marked as 'seen':



This 2nd image shows the button that marks all tweets as 'seen':

Would it be alright if the 140 charas could be extended to 150 or 155 or so charas? For those of us (*raises hand*) who give rather extensive messages, the extension of the minimal character usage to a more usable space for longer messages would be very useful. Thank you. 9-9

I guess the only way to stop this is to delete the messages, but I don't want to do that. So I'm suggesting there should be a way to mark messages as read.

It would be nice if all the messages that came in during the 'off time' would actually buffer/spool, and then when the 'on time' comes around that all the messages that came in the middle of the night could all be sent at once to 'catch up'. All of the messages that I miss in the middle of the night mean that stuff doesn't always make sense in the morning!
