Option to hide register descriptions

**Is your feature request related to a problem? Please describe.**
In "fetch disassembly" view, source and disassembly are shown side-by-side in the source window. Registers are shown to the right of the source window. To conserve horizontal space, I make the variable/memory/registers/etc. pane quite narrow, but this causes the descriptions of the registers ("source index (source for data copies) (64-bit)" etc) to wrap to multiple lines, so that only few registers are shown.

**Describe the solution you'd like**
I'd like an option to hide the descriptions of registers so that no wrap-around happens.

**Describe alternatives you've considered**
Disabling the wrap-around and just letting the descriptions get pushed off the screen while keeping each description a single line would also work.
