Link placeholder / custom name

[tomekit]

It would be great to have syntax (or similar):

[docs](https://example.com)

which would allow to provide custom name for the link.
E.g.: docs

Possibly related: #124

Potentially these regexes could be used: https://davidwells.io/snippets/regex-match-markdown-links

/* Match only links that are fully qualified with https */
const fullLinkOnlyRegex = /^\[([\w\s\d]+)\]\((https?:\/\/[\w\d./?=#]+)\)$/

/* Match full links and relative paths */
const regex = /^\[([\w\s\d]+)\]\(((?:\/|https?:\/\/)[\w\d./?=#]+)\)$/
