Quick menu and placeholder highlighting

Type two semicolons anywhere in a message and the template list appears at the cursor. Keep typing to filter it, Enter to insert, Escape to dismiss.
It is deliberately not a slash. Gmail gives that key to its own writing assistant, and an extension should not take a key away from the application it is running inside.
After inserting, the parts still to fill in are highlighted. Tab jumps between them, and clicking one selects the whole of it so the next thing you type replaces it.
A small bar says how many are left to fill in, and clears itself once the last one is done.
The highlighting exists only in your compose window. It is painted by the browser rather than written into the message, so nothing about it reaches the person you send to.
The five built in designs now mark their fill in slots the same way the template library does.
A rebuilt toolbar popup: what is installed, what you have saved, the keyboard shortcuts, and a link to the free library.
