I see five things that the DL client could use right off the bat
There were actually like a dozen... but all i had to do was play with it for a little while and almost all of those things i wanted were actually already implemented

Kudos on the client, it's a work of brilliance
umm but ya, lemme get on with suggestions, i'll keep it succinct:
1. Save settings feature upon start up
2. allow input window font settings to change colour (its locked yellow right now, i like it black)
3. Make the amount of gold/gold in bank more clear in the notebook, its really hard to read the way it is now
4. Having "Next Level: -6149146" in the notebook instead of typing "attributes" to see it everytime
5. Having the foe info from the notebook as a seperate window, it definitely needs more space, would love to attach it to the upper part of my screen and make it horizontal while the rest of the notebook is vertical on the side
