[GNC] Liabilities and Net Worth in Android app

[Chris]

Dear GnuCash community,

I recently installed the Android app for the first time and played 
around with it. I noticed two things that I am not sure about and wanted 
to ask your opinion/advice.

1. Liabilities

The scenario I am running is a simple credit card. If I use my credit 
card and money is withdrawn from it then my understanding is that I am 
supposed to use the "payment" option for these transactions. This 
results in my liability balance being negative which also leads to the 
correct behavior with the bank account it is coupled to: The said 
"payment" amount booked from my credit card is subtracted from my bank 
account in my assets. Please let me know if I made a mistake in my 
assumptions thus far. If this is the correct behavior then this brings 
me to my second point:

2. Report - Balance Sheet:

2.1
If the above is correct, then in the reports' balance sheet my assets 
are shown in green (positive) and my liabilities in red (negative). But 
this leads to my net worth being calculated as follows: Net Worth = 
Assets - Liabilities with Liabilities being inserted with its negative 
sign and therefore my net worth actually turns out to be adding my 
assets and liabilities instead of subtracting them which is of course 
not correct. Can someone confirm this?

2.2
The second point I want to make is the reports' balance sheet assets 
calculation. I run the following scenario (I would add a screenshot but 
the app does not allow for it):

Cash in Wallet:                        18.75
Checking Account:                   2,386.21
        - Subaccount_1:               2,264.04
        - Subaccount_2:               -83.42
             - Subaccount_2.1:       67.10
             - Subaccount_2.2        -150.52
         - Subaccount_3:              205.59
Savings Account:                     0

Total:                                       2,587.16

Clearly the calculated total amount is wrong. I do not know what is 
calculated here from the information shown. Can someone confirm? The 
correct answer for the total would be 2,404.96 which is also shown when 
I look at my assets account.
(Side note: I would also recommend adding some visual distinction for 
subaccounts in the report balance sheet. Currently all is shown plain 
with the same indentation.)

Thanks for your help and time in advance!
Chris

PS: I was surprised that the mailing list server does not offer TLS. Of 
course the list is open but it would be nice if in 2019 it would be 
offered since people like me need to turn off "only send emails to TLS 
enabled servers".
