a view showing two texts side-by-side.
|
|
|
32 |
Scrolling is synced, by always scrolling both views.
|
|
|
33 |
This type of view is especially useful to show diff-lists,
|
|
14
|
34 |
code-versions, or other one-by-one vievable texts.
|
|
12
|
35 |
|
|
|
36 |
Usually, it does not make much sense, to put totally different
|
|
24
|
37 |
or unrelated texts into this kind of view.
|
|
|
38 |
|
|
|
