Hello,
You’re right, the UI is a bit different in version 5.2.0.
The search function (finding editable transactions) still exists, as already asked here last month:
- Has the search (through transactions) bar disappeared from ledger interface in version 5.2?
- Kmymoney 5.2 missing searchfield in Kontobuch (account posting)
and the short answer is: press Ctrl+F while being in the ledger.
