CR: Remember control choices from last use #55

Request: When renaming a few files at a time, then selecting others and repeating a similar rename action, it would be great if the app remembers settings from last time (eg whether Replace or Insert was used, if "from end" was checked).

As always, it would be even better if this behaviour can be toggled from a Settings screen.
Or, even better, if a default set of settings could be loaded with each app launch.
Or maybe for a few presets to be saveable, with 1-2 clicks required for selecting a preset from launch. But I'm getting carried away.
