Looking for custom function to select a range

[baldore]

Hello!

I really enjoy using ranges, but it's tedious to put something like :-10,+20 before being able to apply some function. I was wondering how difficult can be to use this plugin to get two lines on the screen and create the range already shown.

I was thinking in something similar to https://github.com/haya14busa/vim-easyoperator-line, where you select 2 lines and then the range appears.

Thanks in advance.
