Yes, such a wallet exists, though it is still in beta: AtomicDEX (desktop version only) supports Namecoin (NMC).
You can even use the built-in “atomic swap” feature to trade your NMC, for example, for Komodo (KMD), which you can hold in the wallet and collect rewards or sell on many popular exchanges like Binance (affiliate link). Make sure you read the instructions first (found under Support). The atomic swap protocol requires that the maker and taker stay online and monitor the blockchains involved.

You’re running an application on a PC with a high DPI display and some (or all) of the controls are too small. You do not want to change the system-wide scaling settings just to make this application more usable.
The solution: Change the app’s high DPI setting
Windows 10 allows you to change the high DPI settings for each application.
Open the application.

Select Properties:
If this method does not work, locate the application’s folder and right-click on the application file (.exe), then select Properties.
Select the Compatibility tab.
Click on Change high DPI settings:
Check the Override high DPI scaling behavior checkbox and select a new setting from the drop-down list:
Confirm both open dialogs with OK.
“System” should solve the issue of some controls being smaller than others), though the app will look a bit blurry. “System (enhanced)” will try to make everything look more crisp. You might want to try out all settings (and you may have to restart the app to see any changes).
