Problem Statement

After update 2.0.3 the new GUI only allows for copying all changed lines or the currently selected changed lines. Clicking on the code only displays those two options. There's no way to copy the old lines. I tried selecting multiple lines to copy and cannot. I want to copy a line changed line and paste it into the prompt to tell claude not to change that line. This worked with the old ui, but new ui broke it, so this could also be filed under bug or regression.

Proposed Solution

Give us back the old terminal UI via a toggle, or let the user select and highlight whatever text they want in the diff.

Alternative Solutions

Workaround woudl be to revert to the older plugin because it's better.
