Is there an existing issue for this feature request?

I have searched the existing issues

Toolchanger users have no way to see the total number of toolchanges in the preview summary stats after slicing. The existing "Filament change times" counter always shows 0 for toolchanger setups because it counts M600-style filament swaps, which toolchangers never use. Toolchangers switch between tools via T0/T1/T2/T3 gcode commands, which are not counted anywhere in the UI.

Which printers will be beneficial to this feature?

All

Describe the solution you'd like

Add a "Tool change times" (or similar label) counter to the preview stats panel that counts the number of tool switches (T0, T1, T2, T3, etc. command transitions) in the generated gcode. This would give toolchanger users the same at-a-glance complexity information that Bambu Studio provides AMS users via its "Filament change times" counter.

Describe alternatives you've considered

Currently the only workaround is to manually search the exported gcode for T0/T1/T2/T3 commands and count them, which is not practical.

Additional context

Toolchanger support has been growing rapidly in OrcaSlicer and I think this would be a small but meaningful qol addition for the community. The data is already available in the sliced gcode — it just needs to be added in the UI stats panel.
