Poll

I'm finishing next revision of TC calculator and almost all the logic paths are now checked and working fine. Previously to the launch I want to ask you something:

What do you prefer, a "Vari" button for specifying variable (non-dropping-frames) speeds or multiple buttons to select them? On one hand "Vari" may be more flexible but on the other hand it's less ergonomic.

Let me know your opinions. Leave a comment ;)
