Yes.

I never saw such a bug, so without code it is all speculation.

Yes, of course, that's why it is open source.

No. 
Just close the designer form while doing that, otherwise the IDE will
overwrite your changes on next save.

Yes, there are some difference. 
In general: Lazarus is only backwards compatible. Projects
edited/created with newer version must not be opened by older
versions.

Have you added the printer4lazarus package?

You can not share the config files in the IDE config directory between
different platforms. Projects and Packages are made for sharing, the
IDE configs are not.

Yes.

These are ok. Although I hope eventually someone will optimize synedit
to not store them if not needed.

Without code no one can tell what is wrong.
This could happen when mixing different lazarus/fpc version.

In this case it might be right.
