Steps to reproduce the behavior:

1. Open k9s with context A
2. Open another page (e.g. namepsaces :ns)
3. Change to context B :ctx B
4. Press CTRL+c
5. Open k9s with context A

Expected behavior
I would like it if the config could be saved from previous contexts. Maybe this could be done when switching context?
