Enhancement: URL option for internal page linking
The main thing currently missing is URL option for internal linking. Only absolute URL is possible, what is, of course, a terrible solution.

I see that as necessary too. Nice solutions are these:
- https://github.com/medienbaecker/kirby-link-field
- https://github.com/OblikStudio/kirby-link-field
I know that the solution is not perfect yet, but it's not true that you can only save absolute URLs. Relative paths are possible as well.
I was previously using SylvainJule's Kirby Markdown Field which has additional options for linking to other pages on your project. I can't wait for this to happen in the Editor.
And maybe option to link to files as well…
The problems that are constantly in the back of my mind also include persistent page and file linking. I know autoid plugin can/could help, but sometimes native funct is better. Link checking becomes a big issue.
I know that the solution is not perfect yet, but it's not true that you can only save absolute URLs. Relative paths are possible as well.
Unfortunately, there is no possibility to link top page from subpage if Kirby install is in the subfolder. Except with absolute URL.
EDIT: Well, pardon me, there is solution. From subpage relative link for top page is: ../toppage
I didn't know this can work for URLs, tested it for fun, and it does. :-)
Adding the possibility to link to an anchor within the page ( hash on <h_n_> for example) would be great too.
Nice to have: Take advantage of the enhancements to add:
- a
targetoption (or checkbox for "Open in a new window") - a
reloption (for noopener, noreferrer, nofollow) - a
classoption
