8.5.5 — Save Details

Your saved box designs just got way more useful. You can now tag any save with:

— The subwoofer it's built for (autocomplete from the sub database, or type your own)
— RMS power per sub
— Target use: SPL, SQ, Daily, Custom — pick one or stack them
— Build notes
— Up to 4 photos (Pro)

When you pick a sub from the database, loading that design later pre-fills the calculator with its T/S parameters and tuning recommendations. No more guessing which sub you built that box for six months ago.

Plus profile bios, an option to keep photo uploads on Wi-Fi only, and various improvements throughout.
