- input text: add ImGuiInputTextFlags_EnterToApply? (off #218)
- input text multi-line: way to dynamically grow the buffer without forcing the user to initially allocate for worse case (follow up on #200)
- input text multi-line: line numbers? status bar? (follow up on #200)
!- input number: large int not reliably supported because of int<>float conversions.
- input number: optional range min/max for Input*() functions
- input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled)
- input number: use mouse wheel to step up/down
