new: next iteration of our local file browser
new: support light/dark OS theme (Windows)
new: +SHIFT key to capture UI layer (PIC,REC buttons)
new: logos and branding images
chg: added hints for zx models
chg: avoid recording UI layer in videos
chg: display dialog titles whenever possible
chg: do not translate games before loading (AfterTheWar)
chg: ESC/RMB presses will cancel the UI top layer (dialog/overlay layer) before switching to game browser
chg: highlighted current selected option whenever possible
chg: increased internal buffers for va() calls
chg: removed Screenshot action from PRINT_SCREEN key mapping
chg: replaced native (i)nfo dialog
chg: simplified makefile: removed embed tool (MAKE)
chg: ZXDB made ids clickable (forwards to SC page)
fix: do not shorten tape silences when TurboROM is enabled (see: Alkatraz/TopoSoft games)
fix: fixed bug that prevented excessively long named games (+128chars) from being included in zxdb listings (TheMojonTwins)
fix: fixed issue2 from being selected within new UI menu
fix: fixed local file browser while identifying some false positive file extensions (like .c)
fix: fixed wrong window priority when displaying search dialog in fullscreen
fix: made xinput library to be loaded dynamically; fixes those installations where DirectX is not pre-installed (Windows)
fix: reduced heuristics for Kempston Mouse detection from (X+Y+MB to X+MB) since Arkanoid does not use Y coord :o)
fix: use AVX in X64 builds and SSE2 in X86 builds (Windows)
wip: toggled different GLX attributes in the hope that hw accelerated surface gets enabled (Linux)

-## About
-Spectral is an experimental emulator that I have been randomly assembling [since the pandemic days](https://twitter.com/r_rlyeh/status/1280964279903158273), inspired by my old fZX32 emulator. Accuracy and performance are long-term goals, but the primary focus is just having fun with this thing. Hardcore ZX users will find little value in this emulator right now, but I hope newbies may find its ease of use somehow appealing to try.
+Spectral is an experimental Sinclair ZX Spectrum emulator from the 80s, which has been randomly assembled [since the pandemic days](https://twitter.com/r_rlyeh/status/1280964279903158273). Accuracy and performance are long-term goals, but the primary focus is just having fun with this thing. Hardcore ZX users will find little value in this emulator right now, but I hope newbies may find its ease of use somehow appealing to try.
 That being said, Spectral has a very compatible TAP/TZX loader and some other interesting features that provide me some fun in these days.
 Code is highly experimental and prone to change in the future. I will keep altering/breaking things randomly for good sake.
