If applied, this commit will stop some configs from panicking

[pop]

Some config options previously raised a panic of the following form:

thread 'main' panicked at 'fatal: no active view', src/session.rs:1293:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace.

The config commands in question include:

• f/resize
• set animation/delay
• slice

Fixes #51

TODO:

I'm not sure if these are worth doing, but I'm aware they're potential issues:

• [ ] Add automated tests
• [ ] Move the session.blank(...) call to Session::new(...) to simplify fn init(...) in lib.rs.

Would have modified blank(...) but it's use in Session::edit(...) put that above my ...

Ahhh, I forgot about this. Your approach makes more sense then. Just follow the recommendation about as_blank, and rename it to with_blank, as that makes a little more sense I think.

Thanks!
