# This array contains my most commonly used apps on f34, cached here
|
|
# for speed. If they don't work for you, you can either just remove
|
|
# these entries and rely on on-the-fly lookup of icons (which may be
|
|
# slow). Or, for speedier operation, you can:
|
|
|
|
# 1. get all your common apps running
|
|
# 2. remove the entries in the array
|
|
# 3. run the script from the CLI
|
|
# 4. copy-paste the list of "[app]=icon" lines into the array
|
|
|
|
# Also, if all else fails, you can hardcode your app here:
