Final jam update for &pex - This is the last few days' work, I replaced the freeform panels with a single tabbed window, added UI elements for the "open" and "highlight" actions, and added a status bar and a list view that shows all the bytes offsets for your primary and annotated selections.

&pex day 2: I added a hotkey to switch between all-hex and hex/ASCII views, and I added an ad-hoc highlighting system, where keys 1-9 on the keyboard are mapped to different colors that you can use to mark up your file interactively.

Day 1 of the Essentials Jam - &pex can open files and view them as hexadecimal bytes, with ASCII characters auto-converted. It's written in Odin, using my premade SDL3_GPU-based platform layer + imgui library. All the app code is of course brand new, inspired by a similar project I had hacked on for an hour or two in a while back, but rewritten from scratch today.
