 #### Planned improvements
 
+- Make better use of the opening view of **Help** tab to explain the gadget.
+  Also add one or more additional tabs with an overview of regular expressions,
+  with links to R4DS and `vignette('regular-expressions', package = 'stringr')`.
+  Maybe also a **Try This** feature that sets the `text` and `pattern` with
+  regex challenges (possibly borrowed from R4DS).
+
+- Add a global search option to the **Regex** tab. Groups would be lost, but I 
+  can still highlight global matches.
+
+- Add "flavors" menu to **Regex** tab. Automatically sets options to common flavors.
+  Mainly for clarity when switching between "base"" style and "tidyverse/stringr" defaults.
+  
+- Add replacement functions somewhere. Maybe to **Output** tab with `g?sub` and 
+  `str_replace(_all)?` as options with an additional "replacement" field that 
+  appears when those are selected. Or possibly as a "flavor" (see above) in the
+  **Regex** tab.
+
 - I may add `stringi` functions to the list of available functions in the **Output** tab.
 
-- I would like to add the regex/function options for the functions in the **Output** tab, similar to the options present in the **Regex** tab.
