Just a note for those who are still struggling with L4 hanging, or lagging, or it's slowness.
I keep finding that resource tabs that do not need to be linked are linked, so that when I scroll up or down in a resource, it scrolls all of the linked resources, and that really slows down the process.
Many of my tabs do not need to be linked, especially if I am accessing them from the passage guide or exegetical guide. The fewer linked tabs, the faster the scrolling.
Also, if there is a resource that is open that you scroll around a lot in, for me my ESV, then have a copy of that open with no links at all to it.
The slower your computer, the more important this is.
I've seen a video mention this as an aside, but had not seen any threads directly related to it.
