Note: This list is obviously not complete.

• test a bit more, see if memory usage has improved

• synchronize scroll position with irssi? or just remember scroll position of inactive windows client-side
• gui for selecting window item in windows with multiple items
• switching of active server for empty windows
• Make entry behave less like the irssi one; so you can actually select text and copy&paste,...
• fix multiple spaces after eachother (change to nbsp)
• fix layout when there are more tabs then window width
• hash password in settings

• show in the client that just-selected-window might not be up-to-date yet
• let client forget what it has of a window when it's not been actived for long, to save memory?
• do something smarter than only following active window?
• make links clickable
• detach irssi window into separate browser window?
• optimise http connection usage: keep two pending clients instead of just one; sending response to older client
• network&server, settings, ignores, hilights, notify, triggers?... config dialogs
  -> make client independent from details, let server send ui description? => any script can provide webssi configuration interface
• split windows (or other window management)
• fe-text doesn't remember monospace attribute
  -> cache format in script instead of fe-text?
  -> or only support it in 'live' messages?
