I often use multiple ‘Comments’ columns, put notes in those, and those can be ‘searched’ in alpha numeric order. Combine that with naming clips and making different bins for those, and you can come up with numerous ways of organising your material.
In its day that was one of the ways that Lightworks was far superior to Avid for long-form projects, with the file card you could make bins with any combination of tags, names and comments. (Ah well, sigh.)
