I did some searching and many users recommend Rofi but looking at man rofi-script it seems to just be a list picker. You pick something from the a list and only one thing runs. On Alfred and Raycast you can have interactive extensions which are essentially keyboard navigable UIs.
- One example looking at the Alfred workflow gallery is Reddit Browser, where you select a subreddit from a list and then it shows of lists of posts, you can press
cmd enterto go back & select another subreddit. - Another one lets you ask questions for chatgpt and shows answers right in the launcher (I’m not necessarily looking for AI extensions).
- This Raycast extension lets you search and create Notion pages.
KRunner perhaps. It doesn’t have such an extensive UI (it’s more like Spotlight) but it’s extensible with search plugins like unit conversions and whatnot.
