Improve wording and icons used in video editor
This goal of this task is to review and improve both the wording and icons used in the video editor.
he trash can icon is used for:
1. "Cut" button
2. "Clear selected segment" button
3. "Clear segments" button
But deleting a segment (same as 2) using the "X"-button at two other places on the same screen. And "Cutting" (same function as 1) uses a "checked-checkbox-style" button in the waveform. ... so there is room for improvement.
