-- @Description: Construct a new instance of a window and buffer using the 'plenary.popup' module.
-- @Params:
-- + `_type` ~ string denoting which context manager is owner of the window.
-- + `placeholder` ~ string allowing for placeholder text to be placed within the buffer when constructed.
-- + `opts` ~ a table of additional options to be provided when constructing the window.
-- @Returns: nil. Constructs a new window and stores the window's ID in a global table.
--
-- @Dev: This function is to be as generic for creating a window whilst allowing for as much customisation over the
-- window/buffer which are to be constructed. Users are to access this function so is not part of the module export.
-- However, it's used by all internal built-ins which are meant to be used by users. Consider a class constructor in
-- C++, this function is akin to that behaviour and is responsible for constructing the window/buffer and ensuring it
-- can be tracked by Vim itself.

-- @Description: Find and replace words within the current buffer.
-- @Params:
-- @Returns: nil.
--
-- @Dev: function is responsible to creating all required buffers to allow full user interaction.
--
-- @Future: implementation may allow for greater user customisation similar to what's found with
-- extensions such as Telescope. For now, it should provide a concrete UI for purpose of design.
