Gmail on Safari ... not quite right

I love me some Apple, but sadly, there are some ...

Safari issues with Gmail's mostly awesome UI ...

• The unix-ey keyboard shortcuts for moving around (j for next message, k for previous, etc) require a click somewhere on the page to start working. I'm not sure where the focus is when the page first loads. (It's not in the search box. As far as I can tell it's nowhere -- maybe in an XMLHTTPRequest?)
• Can't send via keyboard. All browsers (that I've used) share the spacebar-for-focused-button-click shortcut, including Safari. However, the send button on a Gmail message, while it gives a visual indication of taking focus after tabbing from the message input box, does not get clicked when hitting either spacebar or enter. Since it's styled unlike other buttons in Safari, I'm guessing it's actually a link dressed up as a button, which is probably the issue.
• Command-click doesn't open links in a new tab. The equivalent gesture works in Firefox, but Safari opens links in Gmail messages in a new window even when the status bar tells you that clicking the link will open the link in a new tab. I know Google likes to put onclick attributes on links to keep the href from being relevant, and I'm guessing that's the issue here. (Presumably some JavaScript is telling the browser to open a new window.)
• The fancy bottom-right-corner floating indicator of whose messages are hidden off-screen doesn't repaint correctly. When scrolling a long conversation with multiple messages expanded, I frequently end up with a whole gaggle of those little colored labels strewn up and down the right edge of the window. (Luckily the worst they can do over there is hide ads.)
