For a use-case where I've copied thing 1, then I start my Textile, then I go and copy thing 2 from somewhere, and then Textile continues with the remaining steps with thing 1 and thing 2?
(1) When creating the textile, you would add a step to "wait for new clipboard data."
(2) When you run the textile, and it gets to that step, a modal would appear, prompting you to copy the new thing to your clipboard.
(3) Once you've got the new thing on your clipboard, you would go back and click "Continue" on the modal from step 2.
(4) Textile would continue with the new thing on your clipboard.
Is that kind of what you were thinking?
Here's a quick example, and one that I often use with Textile to generate a preview URL based on my current branch:
(1) Start with the output of the command `git branch --show-current` in the `~/code` directory (yielding text like `JIRA-1234/some-feature`).
(2) Replace all `/` characters with `-` (now the text is `JIRA-1234-some-feature`).
(3) Prepend `[preview](https://staging-`, which is the start of a markdown link (now the text is `[preview](https://staging-JIRA-1234-some-feature`).
(4) Append `.example.com)`, which is the end of the markdown link (now the text is `[preview](https://staging-JIRA-1234-some-feature.example.com)`).
(5) Copy the result to my clipboard.
With those steps saved in Textile, I can now click a button to run them over and over again (or use a keyboard shortcut if I assigned one). So no matter which branch I'm on, I'll always get a proper preview link without having to construct it manually myself.
