Transient is one of my favorite packages now. I replaced all my custom keybindings into transient under just one C-j keybinding. Now I have a meaningful popup window with my custom keybindings, so I don't have to remember the less-frequently used bindings. Also, transient has this one cool feature, where you can configure a timeout to delay the popup window, which is also nice.
