Is it possible to implement 7 zip support? E.g. opening a *.7z archive which contains a gds2 file. I would prefer it because it has a better compression algorithm than gzip.
Could be another unique selling proposition of KLayout
I use 7zip but always choose .zip, maximum compression for universal compatibility. I see little difference between .7z and .zip filesizes so have no motivation to "be special".
Then again I do not open layouts from, or try to save into, archive files anyhow. I had no idea this was desirable (is it?).
