LinkCompanion control

[roman-yagodin]

Control with buttons (or dropdown list) for each FolderHistory item, linked to DnnUrlControl instances or other selectors.

Control can also have buttons for: current page, last folder created, user folder, configured folders.

Then button is clicked, tries to set selector control to corresponding folder.

Probably better to have some kind of UI switch (tabs, radiogroup) to focus user on links, provided by the LinkCompanion control.

These could be:

• Current page.
• List of breadcrumb pages?
• List of pages on the same menu level?
• List of last created/modified pages (with autocomplete).
• List of last created/modified files (with autocomplete).
• List of folders (from FolderHistory) with list of files.

Switch state can be checked in codebehind to decide from which control (DnnUrlControl or LinkCompanion) we need to get a link.

It's probably better to implement LinkCompanion using React, not ASP.NET or Razor.

It could be too heavy - it this case, we will just need complete replacement for DnnUrlControl based on React.
