This release adds the ability to view RAM and Flash memory banks, and modify RAM banks. The "file panels" can now load any of the following: SD card, Floppy 1, Floppy 2, RAM, or Flash. The menu in the middle has enabling/disabling visual feedback to tell you which commands are active for how you have it configured. For example, you can't copy a file to flash, but you can copy flash to a file, or copy a file to RAM.
You can also search in memory (RAM or Flash). If you want to find "Hello, World", just enter that. You can search for up to 32 characters. If you need to find hard-to-type bytes, start the search with "#", then type in 2-letter hex codes. Commas are optional. e.g, "#00,55,aa,AA,00FFEF". If you get a successful hit, you can jump to the next hit with 'g'. It does not wrap at the top of memory. Search starts from byte 0 of the currently selected bank if you do 'f', or from where the previous search left off if you do 'g'.
There is a start on documentation (available via link from the main README.md. Also, there are several flash installer utility CSVs, see the "installing.md" documentation.
