Why was start in a specific mode removed as a feature

[Colin]

Hi @letters-s_s! This was discussed over here.

Default Mode settings does not appear in Cursor IDE to change the default setting to Ask mode

Hey there! The Default Mode setting was removed in 2.5. From the changelog: Removed Default Mode setting so each new agent conversation begins fresh. The mode defaults to Agent for each new chat, but can be changed in the Composer.
