My cellphone, the T-Mobile G1, runs Android, and I've been using Seesmic to read my Twitter reading list for the past few weeks. It's a nice piece of software, but coming from Twidroid, there's a few things I'd like to see enhanced:
Add a "Jump to Top" button
Allow me to sync my read tweets with my use of Seesmic Web.
Add a provision so that update notifications only notify the user when the Sync Email flag is on for the phone/device itself (Namely, I turn off email notifications (with the Toggle Settings app) at night so I don't get woken up, but Seesmic still buzzes my phone hourly).
Ping.fm integration (I suspect this is coming soon)
