Version 1.11

- Change qa mapping default to q<C-@>; I found it confusing that I could not record macros into register a any more. To keep the previous mapping, use > :nmap qa <Plug>(PrevInsertRecall)
- Make recall of insertion (q<CTRL-@>, q<CTRL-A>) repeatable.
- Add dependency to ingo-library (vimscript #4433). *** You need to separately install ingo-library (vimscript #4433) version 1.015 (or higher)! ***
