Hey Flo,
try this to speed up working with Ketarin when using the server-softwarelist:
1. import list from server automatically once (server list is empty when opening dialog, so you have to click at least search for "" to get the whole list) or add a button get/update list from server (better than search for "") - the search button could be used for searching in listbox
2. keep entries of list in listbox/memory (maybe save in dbfile where other data is stored), so you don't have reload list from server everytime you just want to choose another app from the list
