From a1396dca1adb81d7ae64afdea440151183b4b48c Mon Sep 17 00:00:00 2001 From: siddhantCodes Date: Wed, 18 Sep 2024 01:10:12 +0530 Subject: [PATCH] Wait for 1s before saving user input to opfs This wait time is not final and can change in future. I personally find that 2s is just too slow to see UI react to my changes (save button appearing, preview becoming stale etc) so I've decided to change it to 1s. This value should be as small as possible but we also want to not burn user's CPU and battery so 1s might be fine. --- components/editor/editor-bundle.js | 2 +- components/editor/editor-bundle.js.map
