Description

Currently, each clickable element in the inspector UI adds it's own event listener. An optimization opportunity here is to replace this mechanic with a single delegate event on the parent node.

This would also fix the second half of #113.

Research direction
The issue proposes replacing individual event listeners on clickable elements within the inspector panel UI with a single event delegate on the parent node. The fix would also address the second half of issue #113. Investigate the current event attachment in the panel UI code, likely located in the HTML template or JavaScript files, and implement a delegated event listener on a common parent element.
