Numbering and Letters on Board
Hi, If you go to SETTINGS and scroll down to Board Settings, it is there as an option to set notation on, I use it, but the numbers and letters are small and a bit difficult to see depending on your other board ptions.
Thank you. I had looked around and couldn't find anything. I feel dumb now.

Is this still working? I'm looking but not found it! Thanks in advance!

Thanks in advance for your answer baddogno, but I thought that it was INSIDE each square of the board. Anyway, thanks!

Technically you are not wrong. 11 years is certainly "over a year".

I have the notation set up as outside board. It shows nicely during the game, but when I try to share it to my soccer thread or Facebook, it appears without notation. Any help with that?
I use Gif Speed Changer to make its faster than actual 30-minute game, if that is any help.

For those it is not working, I have added a workaround.
Click anywhere once the chess board appears, click Inspect Element.
Click on the 'Console' tab in the panel that opens and paste the following code and press enter/ return:
The notations would appear. Close the panel. Need to do every-time in a new tab or Happy Playing. Note: No hack, pure browser based.
function addCss(className, cssText) { const style = document.createElement('style'); style.textContent = cssText; addTo(document.head, className, (cls) => (style.className = cls) && style);}function addNotationCSS() { addCss('prk-x-notation-sheet', `span.prk-notation { position: absolute; right: 0; bottom: 0; margin-right: 2px; margin-bottom: 2px; font-family: 'Chess Sans'; aspect-ratio: 1; width: 20px; border-radius: 50%; display: flex; justify-content: center; }`);}
function getElement(str) { if (typeof str !== 'string') { return str; } const d = document.createElement('div'); d.innerHTML = str; const elt = d.children[0]; return elt;}
function addTo(baap, childCls, childCb, skipIfExists = false) { const child = getElement(childCb(childCls)); const existing = baap.querySelector('.' + childCls);
if (existing) { if (skipIfExists) { return false; } existing.replaceWith(child); return false; } else { baap.append(child); return true; }}
function getBottom() { const clockYs = [...document.querySelectorAll('.clock-component')].map(c => c.getBoundingClientRect().y); if (clockYs.length !== 2) throw new Error('No clock component found');
const [whiteY, blackY] = clockYs; return whiteY > blackY ? 'WHITE' : 'BLACK';}
function notationEffectTimer() { let lastBottom; clearInterval(window.N); const N = window.N = setInterval(() => { let bottom; try { bottom = getBottom(); } catch (e) { return; } if (bottom === lastBottom) return; lastBottom = bottom; notationEffect(); }, 300); return N;}
function notationEffect(MAX = 8) { addNotationCSS(); let bottom; try { bottom = getBottom(); } catch (e) { return; }
let j = bottom === 'WHITE' ? 1 : MAX; const rowInc = bottom === 'WHITE' ? -1 : 1; const colInc = bottom === 'WHITE' ? 1 : -1;
[...document.querySelectorAll('.TheBoard-squares > div')].forEach((col) => { const cl = String.fromCharCode(97 + j - 1); j += colInc; let i = bottom === 'WHITE' ? MAX : 1; [...col.querySelectorAll('& > div')].forEach((square) => { const rl = i; i += rowInc; addTo(square, 'prk-notation', cs => `<span class=${cs}>${cl}${rl}</span>`); }); });}
notationEffectTimer();
I tried looking to see if this had been asked before, but it was to no avail.
Is there a way to have the letters and numbers show up on the side of the chess board when playing a game? I am trying to get better at reading notation, but I always finding myself having to count what square is what. Is there a costum theme or something that would add it to the board?
If not, could it be added as an optional feature? A memeber could check a box in there profile to turn it on or off, or something like that.
