Hello,

1. that is missing, but mostly because nobody needed it yet, and I am not very familiar with repl style languages. I expect it to be implementable with current features.

2. The simplest way to do that is to set the makecmd option, options can be set per buffer, so each C++ buffer can have it set to the compile command for it. You'll get output in the make buffer.

3. I use ctags a lot, and it is well supported, it requires the readtags command that is provided by default in universal-ctags, and needs to be installed manually with the older exuberant ctags. There is no cscope support script AFAIK (although should be possible).
