I’ll add regex too. I’d like to add re2 as a dependency, which is an improved
regular expression library.

What about providing two dialogs for searching? One pop-up dialog with all the checkboxes. The second dialog is docked, like the one in source control now, but with no checkboxes. But, the second one uses the same settings the user selected in the first dialog.

In other programs, I find myself using the same search settings, but dislike the floating dialog. The two dialogs might be the best of both, but would it be confusing for the new user?

Here are some potential settings:

Radio group:
- String Match
- Use Wildcards
- Use Regex

Check:
- Descend hierarchy
- Match case?
- Search invisible?

Are the ones with question marks useful? Would there be any other useful settings?

The limitation is in this API:
