Is your feature request related to a problem? Please describe.
I would like for an effect to render text (or ASCII characters) from left to right, like it's being typed out.

Describe the solution you'd like
Similar to the mirage effect (where text can be rendered one character at a time, only randomly), it would be cool to have text rendered one letter at a time from left to right, so

I use dark background themes on my terminals. In VIM I set bg=dark. The color palette that bitwise uses makes it difficult to see some things (e.g., those in dark blue) on dark bg terms.

Nice tool though!

Would like to have a port of TreeView:

as suggested in #866
