When you read the project it says “Cross-platform real-time collaboration client optimized for business and organizations.”
There is a lot of stuffs not working for that, remember the concept of corporate is the program has to work has the corporate wants, it´s not a personal home chat client, it´s a compay chat client.
1- The spark does not auto start up when windows initiates
if it´s gonna be the main comunication system in a PC it have to auto start up,
2- The save password option, automatic login are disabled by default
3- Log in has invisible, Log in anonymously, ¿are u serious?, this is a corporate chat everybody have to be visual!!
4- Account, give to a client the posibility to create an account?? that buttom shuld not exist
5- Client do not support html text (Color bold and styled text)
6- Need a plugin to set directives to client, directives about how the client it´s gonna work, what options it´s gonna be enabled or disabled.
7- sounds are default disabled, they shuld be enabled
8- Too much use of RAM memory 80.8Mb, my antivirus NOD32 uses 61mb
If someone need that´s options can use a personal client has Pandion, it´s much better than spark for a personal xmpp client use, but Pandion it´s not recomendable for corporate
few years ago i used the spark, i have to abandon it because this, it´s some little details but thouse details are the one who separate a personal client from a corporate, i migrated to BigAntSoft, a real corporate chat solution, the server have not all the posibilities of a XMPP server, but the client is awesome, the server aplicate directives to client to control how the chat client it´s gonna work, you can even control a remote computer by the chat www.bigantsoft.com/ it have a android client too. I´m still waiting the spark client for android maybe in the year 2044??
