Opus 4.6 High

Additional Information

Hello, I’m on windows, since the 2.5.17 update I’ve noticed that the collapsible thinking process is missing entirely ? at least it still exist in 2.5.14 even tough when I clicked it, the collapsible section disappeared entirely. Now with the 2.6.0 update, it seems to be completely removed. It only shows “Thinking” with flashing text.

The issue is that when I use a vague prompt with a high-effort model like Opus 4.6, it can take several minutes to process. With only the “Thinking” indicator, I can’t tell whether it’s still processing or if it’s stuck. I’m using a proxy that sometimes requires me to reset the connection when a tool call gets stuck, so without indicator i kinda confused that is this still thinking or am i stuck like tool call.
