The main purpose of the plugin is to start a discussion on how we could improve the editor in WordPress. This plugin is thus a very opinionated one. The button selection is done with reusable content in mind. All buttons that would results in harmful markup are removed.
The plugin also removes the kitchen sink button. Instead, there is an icon with three dots. Pressing that expands the row to contain all the available buttons. This works better with a responsive page than hard coded lines of buttons which in some widths break into four separate lines.

Editor Buttons Simplified

Editor Buttons Simplified is a simple WordPress plugin that makes adjustments to the TinyMCE editor buttons to make it more usable.

This plugin solves one of my greatest annoyances. Quickly changing the case of selected text. Clients often send text with all caps or no caps and clicking through a ton of text to fix the case is often tedious work. I created this simple but effective plugin to eliminate that chore.
Based on a request I have added a fourth button to add Sentence Case as well. So if you have a large block of text with . ? or ! between sentences it will Cap only the first letter of each sentence.
There is an Options Page to enable or disable any of the buttons.
NEW 
I have also added keyboard shorcuts! 
Ctrl+Shift+L = Lowercase 
Ctrl+Shift+U = Uppercase 
Ctrl+Shift+S = Sentence Case 
Ctrl+Shift+T = Title Case 
(I do not own a mac to test on but command should work according to the TinyMCE documentation)
<h3>Usage</h3>
Highlight the text to be changed. Click the Visual Editor button inside your post/page for the desired effect:
<ul>
<li>UC – Changes selected text to all Uppercase.</li>
<li>lc – Changes selected text to all lowercase.</li>
<li>Sc – Changes selected text to all Sentence case.</li>
<li>Tc – Changes selected text to all Title case.</li>
</ul>
