Feature request: suggestions/completions of paths when opening

[detly]

When I use ctrl+o to open a file, it would be nice if as I type in a path, I could somehow see what existing paths are available for me to open. For me personally, the most expected way would be with tab (like Bash completion), where repeated tabs cycle through some options for completion. Other methods I've seen used:

• show all the next path "components" that match eg. Dotab shows Downloads and Documents in a space below, I can then type the full name that I want or the next letter and hit tab again to complete.
• show a dialog/overlay with a list of possibilities that I can use the arrow keys (or maybe typing as well) to select.
