Feedbacks on Grafana UI

We have been comparing flamgraph representation in both Pyroscope and Grafana. Both look great, our feeling is that Pyroscope's UI is more user friendly.
Here is a couple of unsorted feedbacks:

### Easier zoom in/out

In Pyroscope you can zoom in/out on a particular node with a single click.
To do that in Grafana you need, two clicks: first on the node then on *focus block*

feature request: in Grafana use left click to zoom in/out, use right click to show the menu

### Hover on table view

When you hover a line in the table you have the information about the node. Moreover the line on which we hover is highlighted
You don't have those information in Grafana.

feature request: add the hover in Grafana table

### Clearer hover popup in Pyroscope

We find the hover popup in the flamegraph more readable / clearer in Pyroscope where the information are shown in a formatted table. Whereas in Grafana, its a couple of lines of text.
The content is also easier to understand in Pyroscope: (share of cpu, cpu time, samples) vs (total, self, samples)

In Pyroscope:

In Grafana:

### Gauge in table view

The table view in Pyroscope show colored gauge for *self* and *total* cells. On Grafana you cannot visually identify an eventual bottleneck as you need to read each line.
see: Hover on table view's screenshot.
note: The color is the same in the table and in the flamgraph.

feature request: add the gauge in Grafana table + allow to configure the default colorscheme to use for a given pyroscope data source (*by value* vs *by package*).
