Allow creation of new input panel forms

[ianhd]

I saw someone else requesting the ability to control the placement of an input panel (side of screen)

It would be awesome if we could define whole new input panels with buttons, text boxes and toggles and if those pannels could be placed anywhere on screen. (Side middle top bottom etc)

In my org extended plugin i use a new read only text window and an input plugin to simulate a date picker off a calendar. I use a custom mode to allow for custom keybindings. It would be amazing if i could extend the input panel with custom controls.

Here is an example

I can also modify the text box and have it update on the calendar, BUT I would really like to be able to extend the input box here with controls for manipulating the date etc.
