On the left you can see that there are two tracks in this GPX. On the right you will see the track(s) currently selected in on the satellite image and the coordinates in the bottom half.

Anywhere in the application where you see a red line, you are able to change the size of the panels. To do this, position the mouse cursor over a red line and you will notice the cursor changes shape to form a line. Now, press the left mouse button and adjust to slider to your liking. The position of the screen is saved and the next time it will open with the same settings you last worked with.

When you right-click on the tracks on the left side of the screen, you will be presented with a context menu like the one shown below.

Combine tracks
Is active when more than one track is selected and combines those tracks into one.

Rename track
Gives you the option to give a track a meaningful name

Delete track(s)
Delete the track(s)

Combine All
Combine all tracks into one

Group by date
Group all tracks by date. This function can be handy if you have multiple tracks in one day that you would like to combine.

Split on time gap
This function gives you the option to specify a time gap in minutes (eg 120 minutes). If there is a gap of 120 minutes or more between two track points, an new track will be created. Also when the gap between two points is negative a new track will be created. The last function comes in handy when a GPS does not record date values but only time, such as the older Magellan models.
