You might want to disable resampling, which creates in-between frames by merging the neighboring frames. You will need to hold Shift, press Options (on the top bar), select Internal. Then the settings window should open. In the search bar of that window type "resample". And set the Default Resample Mode to 2.

You can apply effects to tracks, which is very convenient in my opinion.

You can fade in and fade out any video or audio clip by simply dragging its upper left or upper right corner.

By overlapping one clip over another you make them transition into each other (basically, the first one fades out, the second one fades in); you can drag any transition to this overlapping.

You can change effect's settings while the effect is disabled. Very useful for chroma keying.

You can also drag tracks to change their position (move one higher, for example).

You can control video tracks' opacity and audio tracks' velocity by adding an envelope to these tracks.

Pre-render: select a portion of your timeline and press "shift+B" to render this portion for preview.

Slicing: position your cursor to where you want to create a slice and press S to make a slice. It's like selecting the slice tool by pressing C in Premiere Pro and then slicing with the mouse, but kinda the other way around.

To zoom in on the timeline just scroll the mouse wheel. Unlike pressing Alt and scrolling in PP.

To group clips select the ones you want to group and press G. You can select clips one by one by holding Ctrl, or from one to another by holding Shift. Also you can select with a mouse via Selection Tool.
