Changes ✨

Config:

• Add _FILES setting for configuring the shortcut that launches your File Manager app.

Logic:

• &crumb should always use retro-tap, irrespective of the THUMB_FORGIVENESS setting.

Combos:

• Base: add one-shot sticky shift on T1+T4 combo, CapsWord on T4+T5, CapsLock on T5+T6.
• Base: move Alt-Tab to LT2+LT5, Ctrl-Tab to LT2+LT3, Hyper to RT2+RT5, Meh to RT2+RT3.
• Base: add Win-Tab to LT1+LT5 combo, Turbo to RT1+RT5.
• Base: add Typing layer toggle combo on RT3+RT6, like Gaming layer toggle on LT3+LT6.

Alphas:

• Enthium: move B/V to pinky home lateral, Q/Z to pinky upper row; tolerable one-handed QU.

Layers:

• Base: put Backspace on RT1 and Enter on RT5 because I keep on wanting it that way.
• Base: remove unused function row, traditional pinky shifts, base layer arrows, etc.
• Base: move Home/End/Page to avoid ulnar deviation on reaching for outer left corner.
• Base: move repetition / Typing layer access key to T6; free up T2 from double-duty.
• Base: add normal left/right Shift on T2. You can easily change this to AltGr (#29).
• Cursor/Number/Layer: rearrange Spacegrams to be more reachable from the T2+T3 combo.
• Cursor: remove Alt/Ctrl/Win-Tab keys on the left thumb cluster; use combos instead.
• Cursor: remove _C(J) shortcut key (labeled "Downloads") since it's not in The Table.
• Number: move Pipe above Gkj stack for Vim; move AT to lower corner, Tilde to cliff.
• Number: move A-E hex digits on right half's function row; F is already on left half.
• Gaming: move square brackets to right satellites for consistency with Number layer.
• Spacegram operators: swap Space and Tab to bring Space closer to Backspace and Delete.
• Symbol: make square brackets easier to access by moving them down to the upper row.
• Symbol: rearrange Spacegram operators, text selection, home/end; remove undo/redo keys.
• Symbol/System/Mouse: move sticky home row mods to number row, step/jump to satellites.
• System: move Lock/Sleep/Power keys to home row; stack RGB controls, mirror similarity.
• Emoji: revert location of shift modifier to T4 (like it used to be back in release v39).
• Mouse: reduce Fast speed from 4x to 3x.
• Mouse: reduce Slow speed from 4x to 9x.
• World: add native compose sequences for French letter OE.
• World: remove unused French letter OE macro under the O cluster (it's already under E).
• Typing: assign &trans to the T2,T3,T6 keys so that they inherit from the Base layer.
