;;
;; Change Log:
;;
+ ;; * 2016-01-30 1.1.1 Ken Manheimer:
+ ;; - shake out initial multishell-list glitches:
+ ;; - (Offer to) delete shell buffer, if present, when deleting entry.
+ ;; - Set recency (numeric rank) as initial sort field
+ ;; - Recompute list on most operations that affect the order, and try to
+ ;; preserve stability. (Kludgy solution, needs work.)
+ ;; - Set version to 1.1.1 - multishell-list addition should have been 1.1.0.
;; * 2016-01-30 1.0.9 Ken Manheimer:
;; - Add multishell-list for managing the collection of current and
;; history-registered shells: edit, delete, and switch/pop to entries.
;;
;; TODO and Known Issues:
;;
+ ;; * Add mouse actions - buttons - to multishell-list entries
+ ;; - see buf-menu.el, eg Buffer-menu-mouse-select
+ ;; * Resolve multishell-list sort glitches:
+ ;; - Fix config so multishell-list-revert-buffer-kludge is not needed
+ ;; - Make multishell-list-edit-entry in-place, so changed entries recency
+ ;; doesn't change.
+ ;; - Fill in kill-buffer prompting gaps, eg if default live-process
+ ;; prompts are inhibited.
;; * Add custom shell launch prep actions
;; - for, eg, port knocking, interface activations
;; - shell commands to execute when shell name or path matches a regexp
;; - list of (regexp, which - name, path, or both, command)
;; * Adapt multishell-list facilities for all-completions
;; - See info on minibuffer-completion-help, display-completion-list
- ;; - implement markup for mouse selection
;; * Investigate whether we can recognize and provide for failed hops.
;; - Tramp doesn't provide useful reactions for any hop but the first
;; - Might be stuff we can do to detect and convey failures?
