gdbmi.nvim's Issues

Enhance gdb prompt with nvim prompt

Such as, use nvim window/denite to browse and edit gdb history

Improve for flexible jump window

Currently, always using the number 1 window to jump.
But if set a breakpoint or frame up/down in another window, it shouldn't change the position of number 1 window
