Inspector Improvements Tracking Issue

[mitchellh]

This is a tracking issue for multiple improvements that can be made to the inspector. If you start working on any of these, feel free to open a new dedicated issue for the task. Otherwise, we can use this as a holding ground for future work.

A lot of these are very contributor friendly. This is a great place to start hacking on Ghostty if you're interested.

• macos: support opening the inspector in a pop-up window (as Linux does now)
• macos: support opening the inspector in a horizontal split
• macos: support opening in a split by extending the window instead of shrinking the terminal
• macos: scrolling with touchpad is too fast (Scrolling on MacOS with Touchpad in Terminal Inspector too fast #1375)
• linux/macos: support monitor DPI for font scaling
• add ability to change font family and size (Inspector: Ability to choose font #1097, Inspector: Allow font size changes #1095)
• list traversal (i.e. in Terminal IO tab) should support arrow keys (Inspector: Allow list traversal with arrow keys #1096)
• add copy to clipboard button for terminal IO (Inspector: Add "Copy" to clipboard button to Terminal IO #1092)
• add semantic prompt row flags to the inspector
• add visual indicator of some sort to show what terminal an inspector is associated with (Cell picker doesn't catch click on cell of other tab #1386)
• show termios configuration (inspector: prevent displaying key events when echo is off #2587)
• show indication that echo is off for keyboard input (inspector: prevent displaying key events when echo is off #2587)

Here is another one: Show picked cell string (not just the Codepoint value). I saw in the source code now that there is a NOTE regarding this in Inspector.zig

Would be useful to show if the terminal is in raw mode.

Bug: Place the mouse cursor where the inspector would open, then open the inspector. Don't move the mouse cursor. Ghostty is now in a weird state:

• You can't type into the terminal because it isn't focused, but you also can't scroll the inspector
• If you left click, the inspector's tab bar (Screen/Modes/etc.) changes from blue to black

While I was testing this (1 window with 3 tabs, all with the inspector open), Ghostty crashed (commit b38c587). I submitted the crash report (ef083305-0749-4595-31f3-2bd4b4b57eab.ghosttycrash).

Another bug: Font size (points) shows a large positive or negative value
