A charger with multiple ports that allows multiple batteries to be charged simultaneously enables you to select the program flow
to be displayed, based on the connected battery and its device data output, using the arrows next to it.
However, this dropdown menu may also represent a configuration that, for example, corresponds to specific properties in telemetry data. In the case of a configuration, the device description contains the relevant links. Different configurations can also be selected using the arrows.

Each configuration is associated with the statistical processing of data relevant to its intended use.
For example, this includes the duration of the motor runtime, the power consumption during that time, the maximum height reached, or ...
The application remembers which outlet or configuration was last used and restores that selection the next time the program is started, depending on the device.
The data set to be displayed can be selected be the other combo box. Analog to the outlet channel/configuration there are buttons to switch to previous or next data set if applicable.

At the left hand side there are buttons to enable data set name editing or deletion. After pushing the edit button the cursor within the data set name field is activated for editing, a hit to enter commits this operations.

The buttons for cropping the dataset are always active and have been moved here. In earlier versions, cropping was only possible when zoomed in, therefore the buttons were located in the corresponding toolbar.
