Hi all,
something about CodeMirror theming:
There are lots of CodeMirror themes available for import in your tiddlywiki
If you install the CodeMirror plugin and open the ControlPanel, switch to "Settings" > "CodeMirror" , there's a link "Usage information" with a how-to for adding themes
about search functionality:
The "Search and Replace" CodeMirror plugin adds a search panel within the Text Editor that lets you search your Tiddler-Text, highlights the search results and lets you cycle through them.
Hope this helps,
BTC
