Disable past specs and minor tweaks

[ahuang11]

1. Hides the retry icon + disable codeeditor if new message input as to not contaminate memory, until we have a good replay plan

2. enum had a bug where if it was numeric, it would crash
3. there was uneven spacing between each icon so I added a spacer.
