### Fixed
|

|
- Many potential network and display race conditions eliminated
|

|
- Whether a tab is loading stays indicated when you switch away from it and go back

- Plain text documents are displayed faithfully (there were some edge conditions)

|
||||||
- Simplify into one struct
|
- URL for each tab should not be stored as a string - in the current code there's lots of reparsing the URL
|
||||||
- All the maps and stuff could be replaced with a `Tab` struct
|
|
||||||
- And then just one single map of tab number to `Tab`
|
## Issues
|
||||||
- URL for each tab should not be stored as a string - in the current code there's lots of reparsing the URL
|
- Can't go back or do other things while page is loading - need a way to stop `handleURL`
|
||||||
|
- Change renderer to start style tags on each new line of wrapped link, to prevent left margin from being highlighted
|
||||||
|
