drag column separator with mouse to resize previous column

[midichef]

Is drag-to-resize a feature worth having? Sometimes I want to resize to an approximate width and I have to discover it by using z_ repeatedly with different numbers, trying to find the right size I want: z_ 10 z_ 8 z_ 7.

Or maybe z_ should interpret a click as a resize?

I have the same problem with z_ so I would be interested in this. But as always the amount and complexity of the code will make or break a feature. If you can do this in 3 lines of code, absolutely, that would be great. 10 lines of code, probably worth it, especially if they're in one place and easily understandable. 30 lines of code, likely okay, but it should be isolated in the features directory, so it can be removed or disabled without disturbing anything else. 100 lines of code for this feature and I'd put it in the experimental directory, only moving it after people have used it extensively and will vouch for it. 300 lines of code, not worth it.

Also remember z- which halves a column width. So for very wide columns, sometimes I'll do _ to get the max and then z- a few times to whittle it down. Maybe we need some commands/bindings for more incremental width adjustment?
