![sorting](assets/sort.png)
#### Tree mode
Use `t` or `F5` to toggle tree mode in a process widget. This is somewhat similar to htop's tree
mode.
![Standard tree](assets/trees_1.png)
Sorting works as well, but it is done per groups of siblings. For example, by CPU%:
![Standard tree](assets/trees_2.png)
You can also still filter processes. Branches that entirely do not match the query are pruned out,
but if a branch contains an element that does match the query, any non-matching elements will instead
just be greyed out, so the tree structure is still maintained:
![Standard tree](assets/trees_3.png)
### Zoom
Using the `+`/`-` keys or the scroll wheel will move the current time intervals of the currently selected widget, and `=` to reset the zoom levels to the default.
