Dragging Samples Tracks & Keyboard Shortcuts Editor

Anything that doesn't fit into other topics goes here!
Hi. I thought of 2 ideas that I think will help people a lot.

1). I think that being able to drag sample-tracks from one window to another, Click+Drag to move them around and shift+Click to clone them. For example dragging a track from Beat/Bassline-Editor to Song-Editor.
It helps a lot since without that feature, people have to go to their samples and find it and then use it.

2). It's not so easy to find out all of LMMS's hotkeys and shortcuts, there for I think it'll be nice if LMMS had a option to open a window like the Settings option, or just that the settings window should have another tab to view and edit all of the hotkeys and shortcuts that LMMS has, because it's a real hack that makes things go faster.
Re 1.) Ctrl-drag works for that. You can move tracks (instrument or sample) between LMMS windows with Ctrl-Drag, if you start dragging from the dragging point on the left.
2.) is a requested feature on the github.
Kindly check the github, lmms, and otherwise to see if what you've requested is already been suggested before.
