Leave breadcrumbs in the key comparison tool
When browsing the key hierarchy in the key comparison tool I would like to add breadcrumbs to keep track of what you are browsing, e.g.: L1_HLT_CONF > L1_TRG_CONF_KEYS > UGT_KEYS > UGT_INFRA_KEYS on the top of the comparison.
I might also make the various entry clickable to quickly get back to parent keys in one step.
