Differentiating between in/out transactions

Currently, as I look through all my transactions, I don’t know whether they are expenses or income. My solution is to filter in google sheets by values (all values less than 0) and then I can see all the expenses. From there, I make another column titled ‘In/Out’. I paste ‘Out’ for all the rows (and then do the same for ‘In’ for all the values above 0).

Seems like a small win, but may be advisable to add a column for ‘Income/Expenses’ as default on the google sheet.
