[TxMt] minor suggestions (1.0.2b3)

[Eric Hsu]

Hi Allan,

A few little suggestions.

1. Find dialogue should remember 'regular expression' setting between 
invocations.
1a. Cool if Find dialogue remembered the last few searches and replaces.
2. Option to subtly highlight current line.
3. FYI. On occasions I can't quite duplicate, the last 'pixel' on the 
right is not displayed. The document gets into that state and 
resizing the window doesn't help. I'll try to collect more data on 
that.

- Eric
