Google Wave: First thoughts.

Some thoughts, put here mostly for my own returning to in the days to come.
I just got my Google Wave invite today, having been nominated about a week ago. I hopped on immediately and dug right in. So far, I'm enjoying it for a number of reasons, not the least of which is that at the moment it resembles in spirit (if not in nature) nothing so much as those heady pre spam-bot days of USENET. Except with more cats. And bacon.
And I have just given far too much hint as to my age.
That said, there are improvements to be made. Please note that I am using Wave on Firefox (attempt was made with Safari, and swiftly run away from) on my MacBook (so, no Chrome) with a high speed connection.
1) There is an archive button, why can't I have a trash button? While dragging Wave to the trash seems to be easier, actually clicking on it and then clicking trash would be far, far easier.
2) Public conversations: Right now they're the lifeblood of Google Wave, and it's a very kludgy process to get them started. There needs to not only be a button to do this with (hey, maybe a 'format wave' button right from the start?) but also a selection of different kinds of public, such as open to contacts only, open to members of certain google groups, open to people with certain tags on their profiles. Or hey, how about groups that are title/description only and you have to click a button to be invited?
3) Private blips: Right now you can only private blip a contact. But if you're in a public wave, that person you want to private blip might not be a contact. Private blips should be available with anyone, unless someone has private blips blocked. Say that five times why don't you?
4) Tags: It is not immediately apparent that the way one normally does tags on most other sites (with commas between the tags) is not the way one does them on Google Wave. I actually like how Wave does it better, but I screwed up a tag before I figured that out. And there was no way to delete the tag. Whoops.
5) Searching. This must be improved. Even knowing the title of a public Wave I could not find it by using straight keyword. Talk to some librarians, Google.
6) Threads need to be more clearly delineated. It gets hard very quickly to tell which thread a reply is in. Perhaps box threads, or make it easier to collapse them within a wave.
7) There needs to be a chat bot or window. The threaded conversations are great but everyone is typing all over the Wave. A chat extension of some sort that then gets saved to the wave would be ideal, especially for the 'social' Waves.
