1.Forget About Shortcode Buttons
In use – responsive – editable – save tamplate – no save content & link – copy-paste does not hold the color
Buttons can be saved (holds a database with all buttons).Very user friendly.
Not responsive on mobile view: You can change the size of the button for the mobile view, but responsive setting reacts globaly (on all buttons). There is no space bettween buttons when changing line (they touch each other). The pro version may have the ability to use responsive setting per button.
3. Buttons Shortcode and widget
no save…not editable after creating the button (only using html)Wishes & Thanks
4. SiteOrigin Widgets Bundle
This plugin contains an editor. You have to use this editor (make it default) in order to add a button (from his toolbar). It is not a flexible solution and changing the default editor may cause damage in the existing pages and posts. Buttons can’t be saved.
5. Ultimate block
This plugin works only with Gutenberg editor. As mentioned above: You have to use this editor (make it default) in order to add a button (from his toolbar). It is not a flexible solution and changing the default editor may cause damage in the existing pages and posts.
6. Shortcodes Ultimate
Can be saved as “Preset” (test if there is a limit).
Editable…after creating the button ( but only from “Preset” option – you have to delete & insert any button separately) Canot edit saved buttons, you have to recreate them.
Mobile responsive (but there is an issue with the line gaps: fixed using css – have to be tested on different smartphone models)
Note: The second “Wishes & Thanks” has different size (purpose: testing sizes). We have to create and save any button with the desired size separately.
