Would be nice to have an arrow option in Lucidchart for process flows so you could create a bidirectional line with both a head and tail arrow.

I added a shape and typed in some text.  I would like to change the shape to something different but retain the text.  Is that possible?

I am using the online version and I cannot find where to disable line jumps. I have multiple intersecting lines and I need them to not have jumps. Can someone please point me to where I can disable this?

I would like to be able to place a border around an image. Not a border placed floating around it (like a container) but one that is stuck to the image. Images look better this way.

Can someone please provide details regarding the same.

It seems like there's no way to lock aspect ratio while resizing an object.

I've found a few hot keys I didn't know about while browsing through the forums (Like ⌥ + mouse to move canvas and ⌘+G to group) and a few are mentioned in UI menus (L for line draw) but is there a master list somewhere?
