1 - When I select text in an entry, I can't copy it to the clipboard.

Do you know if you're compiling with KHTML or not? That may make a difference. There should be a right-click context menu command to copy text in the entry view. I'm also able to select text and then middle-click to paste.

I've run into this before as well.  Not a big enough deal to report it, but it'd be nice to be able to use ctrl-c to copy text instead of having to use the context menu.  Like I said, not that big a deal when you know how to work around it, but just weird and unexpected behavior given how ubiquitous ctrl-c is.  Would be nice to have that work if there's some simple way to implement.
