 Change Log
+Version 0.2.0 2019-XX-XX
+Major update:
+New Features
+
+    Added the ability to work on content-editable elements. Previously it worked only with text boxes and input fields
+    Added symbol menu with roughly 70 symbols and submenus. (Why it's useful to use in rich text elements now).
+    Corrected errors in Markdown menu.
+    Added install, update, and uninstall pages with poll.
+
+Issues
+
+    Content-editable element capabilities only work on secure (https://) not inscure (http://) pages, because they require (for now) the navigator.clipboard API, which does not work on inscure (http://) pages.
