Nice idea!
2. ## cd plus for Alfred

I write a workflow for opening files/directories either in Finder or in iTerm directly with Alfred. It supports saving history records and auto-suggestions according to the history records. Hope you like it Description This workflow could help you: open the given path/file in Finder (cmd) reveal the given path/file in Finder (ctrl) open the given path/file in iTerm It can remember at most MAX_LENGTH history records that you searched before and you can access them again conveniently. Download You can download the workflow file from my GitHub.﻿ Examples cd + nothing : It will list all the history records. cd + path/file name : It will open the path in Finder or open the file directly. cd + any string : It will list all history records that are possibly relevant to the input. cd + path/file name & press command while selecting an item in the list : It will reveal the path/file in Finder. cd + path/file name & press ctrl while selecting an item in the list : It will open the path/path of file in iTerm. Note : Please make sure you have installed iTerm before you try this !
3. ## Simplify fractions

Hi, I added support for German comma as a decimal point just now. You can try the updated workflow here.
4. ## Simplify fractions

@CJK Thank you for the suggestions! I will consider adding these features later :)
5. ## Simplify fractions

I write a workflow for converting a given decimal to a simplified fraction as well as simplifying a given fraction. It saves me a lot of time and I hope it is useful for you too. Download You can download the workflow file from my GitHub. Examples frac .11 ==> .11 = 11 / 100 frac 4/6 ==> 4/6 = 2 / 3 frac -1.4/2.2 ==> -1.4/2.2 = -7 / 11 frac 1.2/0 ==> Error: divided by zero. frac b/3 ==> Error: Invalid input format ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Update 7 additional math tools are added and the new workflow is renamed to MathTools. 1) Simplify fractions Examples: frac .11 ==> .11 = 11 / 100 frac 4/6 ==> 4/6 = 2 / 3 frac -1.4/2.2 ==> -1.4/2.2 = -7 / 11 2) Greatest common divisor Examples: 3) Least common multiple Examples: 4) Simplify surds Examples: sqrt .0144 ==> √(.0144) = 3/25 = 0.12 sqrt 4 8/81 ==> ³√(8/81) = (2/3) ³√(1/3) Note: 5) Log functions Examples: log 5 ==> log₁₀(5) = 0.698970004336 log2 1.0001 ==> log₂(1.0001) = 0.000144262291095 ln e ==> ln(e) = 1.0 Note: 6) Prime factorization Examples: factor 100 ==> factor(100) = [1, 2, 2, 5, 5] factor 31 ==> factor(31) = [1, 31] Note: 7) Permutations and Combinations Examples: C( 4 2 ==> C(4, 2) = 6 c( 1000 3 ==> C(1000, 3) = 166167000 P( 4 2 ==> P(4, 2) = 12 p( 1000 3 ==> P(1000, 3) = 997002000 Note:
