Description

While ELF and PE are (supposedly?) limited to 8 bytes for section names, Mach-O allows 16, and Mach-O binaries very frequently make use of all 16 of them. Universally so in Objective-C binaries and libraries.

When trying to quickly jump to a specific __objc_class... or related section, this results in the following:

Which requires manually resizing the column every time a new view is opened. This quickly becomes a papercut when repeatedly opening views for multiple ObjC files.

Research direction

Start by locating the memory map widget and the code that initializes the section-name column width. Adjust the behavior so 16-character Mach-O section names are visible without manual resizing, then verify the result with a Mach-O binary containing long section names.
