FibroJedi's Sticky Preview and Publish Buttons

= Where is it intended to be used? FJ-SPPB is a back office plugin and has not been tested with Gutenberg features. Others are welcome to modify it to suit their needs. But I originally made this for me, and I use Classic Editor, so that's its main focus. This tiny plugin's primary role is to create a tab on the right hand side of page/post editor, containing the key "publishing" actions that usually sit at the top of the editor. As you scroll down the page - or writing your content makes the page longer - FJ-SPPB scrolls with you.

Nope. The tab is in addition to it so you can control where your interface items go.

As I made this for myself originally, there are a few other features, most of which can be switched off if you do not want them:

• Word Count at the last save/publish action.
• Close for Now: depending on your window size, this will either be a [X] or a circular (X) symbol. This hides the tab until the next save/publish action.
• Confirmation Dialog: get prompted when pressing [Save Draft], [Update] or [Publish]. You can enable/disable this in options.

• Colour Option! The first personalisation option has arrived: setting the border colour! Just choose from the colour pallet in options.
• Compact Mode: In case off-screen still takes up too much screen-space, you can now enable Compact Mode for a slimline tab.
• Enable per Post Type the tab is not necessarily helpful for all your post types. You can now show it on only the types of content where you need it most.
• Word Count: Show the approximate word count of the current article/page based on the previous save.
• Positioning: Decide how far down the screen you want the tab to appear.
• Opacity of the tab when a cursor is not over it.
• Publish/Update Confirmation option, so you have a second or two to be sure of the updates you've made.
• Enable Beta Features: sometimes issues can't be properly tested until others do it. Enable Beta Features tells you what the current "thing" is and lets you opt in - and out again.

• Exclude Shortcodes from Word Count: Currently, SPPB expands most shortcodes before calculating the estimated Word Count. But you may not want all shortcodes excluded. I'm open to suggestions on future features, but it already does what I wanted it to. I didn't want to overdo the settings. It might be other features would be better done as add-on plugins.
