At the moment any Stomp or Effects setting can be saved as a preset by dragging the block to the presets window. This works well, although it would be much better for my workflow to be able to save a preset by right clicking and naming it rather than dragging and dropping then locating the dropped preset in the list window.
However, an even bigger issue for me is that you can't tweak an existing preset and save the results as an updated version. Instead you currently need to drag the adjusted settings to the presets window. Find it. Find the original version and then delete the original. It would be MUCH more efficient to be able to save presets in the same way as rigs. Store, Store in Local Library or duplicate. Where duplicate functions the way the current drag and drop works but Store or Store in Local Library simply replace the current preset with the amended version.
