Thanks for sharing your thoughts about LibrePCB.

Regarding your questions:

> [@MCollins-Lowell](#):
>
> Are copper pours supported?

I’m not sure what you mean exactly with copper pours - AFAIK this is just a different name for planes, or what would you expect to be different?

> [@MCollins-Lowell](#):

> Is it possible to edit a trace once it’s been placed?

Not yet.

> [@MCollins-Lowell](#):

> Is there a simpler way to alter layer selection when routing traces than having to use the pull-down menu?

You can change the layer with the shortcuts ‘1’ and ‘7’ (will be changed in the next release).

> [@MCollins-Lowell](#):
>
> Does the trace editor support a progressive undo function?

Nope.

> [@MCollins-Lowell](#):
>
> Is DXF import supported for package pad layout?

No, pads cannot be imported. Do you have an example how this works in other EDA tools?

> [@MCollins-Lowell](#):
>
> Is it possible to specify package pad coordinates in a text file?

No.

> Can silkscreen layer elements be manually moved and selectively displayed? The ability to reposition reference designators is particularly important since by default they will often overlap other components, mounting holes, etc… Except in rare cases, device types (names) add only clutter to a layout so are generally omitted.

Text elements can be moved, modified and deleted each separately. But other elements (e.g. polygons) not.

> Is there a simple way to view coordinates of individual pads associated with a component?

No.

> [@MCollins-Lowell](#):

> Color code silk screen layers so that component layer is unambiguously identified.

👍 Unfortunately it’s really not easy to define a reasonable color set for all the dozens of layers…

> [@MCollins-Lowell](#):

> Support palettes for the following attributes/elements:

Yeah I already had this idea as well. But I for routing mode and grid spacing I think it’s not needed anymore because in the next release these can easily be changed with keyboard shortcuts (with unique shortcuts for all routing modes, so no cycling through the modes is needed anymore).

> [@MCollins-Lowell](#):

> Provide symbol and package previews when selecting components from libraries.

Where is the preview missing? At least almost everywhere there should already be a preview shown…

> [@MCollins-Lowell](#):

> Provide support for user-defined hotkeys.

Already implemented for the next release, see [Hotkeys, anyone? - #16 by ubruhin](https://librepcb.discourse.group/t/hotkeys-anyone/229/16)
