Never change the source link page. It is amazing now.
I have added ~7.5 crap-ton* of names in Family Search, about 10 in Ancestry and some other amount in My Heritage.
Every time I link a source to someone, I take a beat to appreciate Family Search's source linker. It is - by far - the best of the lot. It easily allows me to link to nearby family members, even ones that are not considered immediate family by the document.
(I will admit that getting complex alignments right was tricky but once I got that down, I wouldn't trade FS's linker for anything.)
In contrast, Ancestry only lets us link the most immediate family and even then, only when they're recognized by the document as immediate. This would not include, for example, a spouse's parents. In all other cases, we must manually open each person's profile and manually link them to the document. It can be quite tedious.
So please don't change your source linker FS. My soul can only stand so much crushing.
*That's a US (or short) crap-ton of 2000 names. An imperial crap-ton would be 2240 names and metric is about 2204.
