Is there a way to add custom aspect ratios in the image editor? We'd like to add a custom aspect ratio to the list of aspect aspect ratios in the image editor so our client doesn't have to look it up to remember each time. Is this possible?
This will be possible using a new imageEditorRatios config setting that is coming in Craft 3.5 (due to release in early August 2020):
...
'imageEditorRatios' =&gt; [
    'Unconstrained' =&gt; 'none',
    'Original' =&gt; 'original',
    'Square' =&gt; 1,
    '16:9' =&gt; 1.78,
    '10:8' =&gt; 1.25,
    '7:5' =&gt; 1.4,
    '4:3' =&gt; 1.33,
    '5:3' =&gt; 1.67,
    '3:2' =&gt; 1.5,
    'Some custom ratio' =&gt; 1.9,
];
