The app looks and feels great. One thing that I think would be a great boon would be adding some more advanced search features. If I’m not mistaken, it just looks for words that exist linearly in a file. Some things that would be useful include:
regex
operators (||, &&)
wildcards (*, ?)
quotes to search for full phrases (I know fuzzy search is planned)
specifiers (e.g. tag:markdown to search for files containing the “markdown” tag)
