@Max-Raile Do you mean 'Parent/Child'? If you do, click on the hamburger menu for a track, select 'Edit Visible Button Set' then put a check mark in 'Make Compositing Parent' and 'Make Compositing Child'. Then click OK.
@Max-Raile Select the clips then press G. The clips will then be connected until you select them and press U.
That's not really what i meant, a like blue bar came up when i tryied to put the clips togheter and that helped me aline them. the blue bar dosen't show anymore because i must have accidently pressed something
