I can set the Scheduled Transactions column widths to get all the info on screen. 
However, when I re-enter Scheduled Transactions, the default settings have returned. 
KMM 5.1.3
Cinnamon v: 6.4.8
Linux Mint 22.2 Zara
Ubuntu 24.04 noble
I am pretty sure that this has been fixed in a newer version of KMyMoney (e.g. 5.2+).
Ipwixard, thanks for the super-speedy response.
I’ve found a work-around.
Set the columns as preferred then close kmm… settings are then saved
Can confirm this is working as of 5.2.70-059be30
One thing has been missing for almost a year in the Schedule screen is:
It used to be sorted by (Type/Name ASC) then by (date ASC) and was persistent - order would be from top to bottom: Bills, Deposits, Loans, Transfers
For a while now, I can set the order as above, and it will be respected, until the program is closed, and on the next open the order is always: Bills, Deposits, Transfers, Loans.
