@kggthxbai: and anyone else: large fonts are a part of accessibility design. Yes, they're maddening to some of us. But, they're here to stay. Try a search on PluralSight. The search box is like 80px. I could read it from across the room. Many other new sites are the same. ☹️
I have no issues with functionality on the desktop. Browser is Chrome, up-to-date, on Win7 Pro. 24" monitor.
On this tablet, Samsung Galaxy Tab E, (a few years old), I have an issue with the drop-down menus. When opening a menu by short press, the menu doesn't stick open, to allow selection. Instead, the first item is selected. The workaround is to long press until the browser selection dialog appears, then "escape" it to return to the page. Now, the menu is open for selection of the proper item.
Also on this tablet, the board resize thumb doesn't work very well. I had difficulty finding the proper screen area to get hold of it. (I'm using a stylus, but my finger didn't work any better.) Once I did, the resize action was very slow. So slow that I doubted I'd actually completed the action. Perhaps, it would be possible to put it on the outside edge of the board.
Overall, the site is very nicely done. Of the 4 sites on which I have accounts - others being ChessBase,
chess.com,
freechess.org - this site is far and away the best looking. Thanks.
