With the KDE SC 4.13 release soon, a few new features made it into Konsole.
- There have been quite a few requests dealing with the tabs over the years. Now, Konsole can load a stylesheet .css file that will be applied the the tabbar. This can control the size, colors, and text among a few items.
There's a section in the Handbook which gives a few examples.
- Profiles can now store the desired column and row sizes. This is for new windows only.
Configure Current Profile->General
Please provide any feedback on these or any other issues with recent Konsole versions.
