It's a good idea of you, but it's the intention that the columns of the table should always be filled down to the bottom, because it simply looks nicer that way, even if sometimes some icons can't be displayed.

In general, it is much easier if you could create a separate pull request for each change. If a lot of things are changed in a single pull request, it makes the review much more cumbersome. If there is something in this single pull request that doesn't fit, everything can't be merged, even if there may be good things in it.

In addition, nearly all of the icons have a transparent motive so that the background shines through
e.g.

The white "G" is not transparent:

This is important to have a good consistency to the other icons in the theme.

The icon also seems to have a gradient which is not that common in the Material Design Pattern. It would be great if you could check, if it also works without the gradient.

Have you made sure that the following icon works with a dark background?

Because of the grey color that you use here.

In addition, the distances between the squares are too small. They are very difficult to see in the small view of File Explorer in VS Code.

All good. Will open individual PRs with the changes later and we can take it from there. Thank you!
