Here's another idea for RX filters.
An easy way to adjust RX filters on the fly for people with mice with third wheel. When the mouse cursor is over the trapezoid for RX filter setting why not have the center mouse wheel change from VFO control to being able to change the filter? For example - position the cursor on the left arrow in the trapezoid pop-up and have the mouse wheel step that side of the filter in or out. Set up step sizes based on modes. Smaller for CW and digital and larger for SSB. Put the cursor in the center of the trapezoid and it would adjust total bandwidth wider or narrower.
The left click, hold, and drag lacks accuracy.
