[TxMt] Tabs and bundle question

[Tim Fong]

Hi, I had two questions.  

1- sometimes I cannot open a file in a tab. Even when I create a tab and press Open, text ate opens a brand new window. I would like to keep those files a tab away. 

2- I want to create a bundle that will correct for the correct syntax (spelling and end brackets) for an XML like markup. I tried to look at how JSON and XML bundles were done but was overwhelmed. What's the best place to get started?  The markup is called AIML 2.0

Thanks!
