What do you do when there is no favicon, or it looks like this? https://www.marginalia.nu/favicon.ico

A naive solution could be to just display the first letter of whatever the user has named the given link. Not as helpful as a favicon, but it will prevent the page from looking broken if a bunch of favicons don't exist.

Lots of options: Opera on android generates a favicon if the domain is less than 6 letters just from the letters. Use of colors (hashed from the name I guess) also goes a long way.

No way to fix ugly favicons though. Name of of domain can still be used as well.

This is a great point. The chrome extension I was using before building Linkidex had a fixed layout, and I was often times able to quickly navigate it without reading what I was clicking on because I had memorized where certain things were.

the first UI I built with Linkidex was a grid instead of rows. I moved to rows because the grid became tedious for users to parse when they began to search or filter and grid elements started shuffling.

Linkidex does not currently get a sites Favicons, and currently doesn't have a way to fix where a given Link is on the page. I have catalogued this feedback thank you.
