I'm new to SlickEdit, and love it! It does what I always wanted emacs or Eclipse to do. It seems pretty close to perfect, except for a couple of stumbling blocks I've found in my conversion from Emacs. Maybe some other users can contribute their wishlists here too.
1) Emacs-emulation mode, Ctrl-x Ctrl-b invokes "find-buffer" with a default name of the current buffer you're already editing (or maybe it's the name of the last buffer you loaded? I don't know). You almost certainly don't want to find your current buffer by default! :-) In emacs, ^x^b defaults to the previous buffer you edited. That way you can toggle back and forth between two buffers with a simple ^x^b <return>.
2) Ctrl-x Ctrl-f invokes a nice file browser, but it requires you take your hands off the keyboard to use a mouse to navigate. It would be great if there were a mode that would allow you to load files (with autocomplete) solely from the command line. Again, just like Emacs.
3) In vi insert mode, if I'm typing along and an auto-complete box pops up, ESC just makes the autocomplete box go away, it does not take me out of edit mode. It might be nice for the ESC key to optionally close the autocomplete box AND take me out of edit mode.
4) In vi-mode, if I delete a group of lines and then undo, keep my cursor at the same spot from which I started. For example, go to a block of code, and type "d20d" to delete 20 lines. Then hit "u" to undo. For some reason, your cursor is now on a different line (sometimes several lines away) from where you typed the initial delete command.
5) In Ctrl-x Ctrl-b "find buffer", if I type in the name of the buffer I want, it ignores me. I have to actually highlight it in the combo box. It would be nice if it autocompleted the buffer name from the combo box.
Thanks for listening, and making a great editor!
